Bracken Fern, Pteridium aquilinum

Fiddlehead Fanatics

If poke weed tests your foraging bravery, fiddleheads test your foraging philosophy.

Pokeweed can kill you within hours if you make a mistake and consume some of the root. Fiddleheads might cause cancer, someday, maybe, maybe not.  Humanity has been eating fidddleheads (Pteridium aquilinum) (ter-ID-ee-um ak-wee-LIE-num) since before civilization. Modern science says we shouldn’t have.

Before I let empiricism totally rain on this parade, fiddlehead greens were a rite of spring in the area I grew up. It was one of two things everyone talked about, that and when the ice would sink in Sebago Lake (sah-BAY-go.) Maine’s lakes are glacier dug and very deep, sometimes hundreds of feet. You can tread water in a Maine lake in the summer (both days of it)  getting heat stroke from the neck up and freezing your feet off down below. One reason is the winter ice in a lake sinks all at once. There is no gentle melting like an ice cube in a glass. All the ice sinks at once and slowly melts on the bottom ensuring out-of-state visitors get icicle toes in August. Raffles are held as to the exact day, minute and second the ice sinks. Sebago, as the largest lake in southern Maine, is of prime interest, but only second to coming of fiddleheads. As the snow melts and warm days come around, fiddlehead greens is the talk de spring.

Some families dedicate several weeks to their harvest, cooking and canning. One of the Yankee signs of friendship is to be given a jar of fiddlehead greens long after the season has past. Spouses are more easily loaned. My father adored fiddlehead, my mother did not. He lived to 86 and she is 86 now.  I personally know one family that cannot can enough of them, has been canning them for decades, and are still here… which leads to the intrusion of science.

Animals that do not boil fiddleheads before eating can get cancer from them, such as mice, rats, cattle and raw vegetarians. They are also toxic to horses if fed in the hay over time. In areas where there is a lot of P. aquilinum the culprit chemical, ptaquiloside, can leach into the water supply, and yes, there is an increase of gastric and throat cancers in people who live in those areas… read a lot of the chemical over time.

On the other side is the argument that boiling the ferns — read cooking them throughly — takes care of that problem, or lessens it to an acceptable risk level. That said, it is good they only come in great amounts in the springtime for a diet of them will also reduce your thiamine level and can cause beriberi, Clearly moderation is wise.  Personally, I hunt Florida fiddleheads. I think nearly everything causes cancer and I am willing to risk a few fiddleheads with butter once or twice a spring, which is about as often as I can collect enough in this warm place.

The roots of the Pteridium aquilinum also have been used to brew beer, and the root starch used like arrowroot. Bread can be made out of dried and powered roots, either by themselves or with flour. Indians baked the roots then peeled and ate them or pounded them into flour removing fibers.

Cinnamon Fern

Unless you live in a desert or on constant ice, there is a fiddlehead-producing fern near you. Besides the P. aquilinum, which ranges around the world and has for 55 million years, there are at least three other ferns with edible fiddle heads: The cinnamon fern, Osmunda cinnamomea;  the Ostrich fern, Matteuccia struthiopteris, very common in the northeast; and the Sensitive fern, Onoclea sensibilis. There are also a few ferns that are used for tea in North America: Maidenhair fern, Adiantum capilillus-veneris and Adiantum pedatum; Cliff Brake, Pellea mucronata and Pellea ornithropus;  the Sword Fern or Holly Fern, Polystichum munitum. Two northwest ferns, Polpodium glycyrrhiza and Polpodium vulgare have useable roots. By the way Tide Head, New Brunswick, bills itself as the Fiddlehead Capital of the World.

Lastly, there are two ferns found only in Florida and Puerto Rico that have edible fiddleheads, one is rare, one common. The rare one is Acrostichum aureum (ack-row-STISH-um AW-ree-um.) Acrostichum is a combination of two greek words, akros (tipl) and stichos (a row.) Aureum is Latin for gold, or golden. Terminal row of gold. The frond can indeed look golden.

Also called the Coast Leather Fern and Golden Leather Fern, it can be found on the Mainland,  in the Keys, in swamps, salt marshes, brackish canals and sinkholes.  It’s a coarse fern with stiff fronds, up to seven feet or more long. The upper leaflets of the spore-bearing leaves are clearly covered on the underside with golden brown spores. The uncoiling new leaves, the fiddleheads, are quite tender and resemble asparagus in taste. They are a bit mucilaginous. They can be eaten raw or cooked. However, while not endangered, it is usually found only under cultivation. Graze accordingly.

It’s cousin, Acrostichum danaeifolium, is a different matter. Called the Giant Leather Fern and Inland Leather Fern. It is the behemoth fern of Florida, eight feet high, 10 feet across, found in the same environment as its cousin. Its fiddle head is also edible.  Danaeifolium (dan-ay-ee-FOH-lee-um) means leaves like the Danaea fern. Danae is named for the mythological Greek daughter of the King of Argon.

It’s not too hard to tell them apart? A. Danaeifolium is very common and huge. It’s the one you most likely find. It  has red spores under the leaves that  remind you of suede. It’s leaves are close together.  A. aureum is smaller, leaves are farther apart,  and has golden spores under the leaves. Leaf spacing is the most dependable difference.

 Green Deane’s “Itemized” Plant Profile

IDENTIFICATION:Bracken: only large northern fern with a three part form on one tall stalk. Other large ferns have single fronds rising from  deep many-branched root. Leaves horizontal, broad, triangle-shaped; leaflets opposite, lower two larger and twice-divided, upper ones usually once-divided; spores in linear strips under leaf near edges. Cinnamon ferns are easily identified by their cinnamon-colored non-leaflike fertile fronds

TIME OF YEAR: Spring, but in some climates constantly

ENVIRONMENT: Woodlands, well-drained soil that holds water

METHOD OF PREPARATION: Fiddleheads under two inches only. Remove any yellow/brown skin, boil sprouts twice with a change of water between boilings. Boil 10 minutes or steam for 20. Gourmets spread a thin layer in a steam basket and steam until just tender crisp.

 Citharexylum fruticosum: Edible Guitar

The Fiddlewood tree is not high on the list of edibles. As some authors state, only kids eat the fruit, lots of seed, sparse on pulp. But it has some personal history to me — remotely — and is also a medicinal tree.

Fiddlewood, Citharexylum fruticosum

First edibility: The fruit resembles red wild cherries when unripe, and perhaps that is where the first disappointment arises. Like the Indian Strawberry the association implies something it is not. (The same thing happens with the Suriname Cherry.)  And the taste of the Fiddlewood fruit when ripe is not great. It depends on how hungry you are though opinions vary. Many like it. The fruit has two stones, is sweet and is available all year in its native range, which is where it is warm

The botanical name is Citharexylum fruticosum (sith-ar-RECKS-sil-lum  froo-tick-OH-sum) a name that can take us on quite a linguistic journey because “cithera” means guitar. So why is it “fiddlewood?”  Almost directly translated the botanical name means “lyre wood shrubby”  Put in better terms it could mean “guitar wood tree” or more directly  “shubby kythera.” (KITH-ah-rah)  Kythera (a lyre is kythara, kith-THA-rah) is also the Greek word from which we get “guitar” … kith-THA-rah… get-TAR…see it? Hear it? The Fiddlewood tree is also called the Guitar Tree. To explain it all we have to go to Greece.

Unripe berries are reddish

One can navigate by sight from the western end of Crete northward to the southern tip of the Greece mainland in The Mani, where the Spartans lived. Cretans and Maniotes call themselves First Brothers and have much in common in dress, cooking and customs.  From Crete’s Gramvousa Peninsula you can see Little Kythera, some 20 miles away. Little Kythera (Antikythera) sits on a fault line and a few decades ago part of the small island rose 20 feet, a change that is still quite visible today. That is also where a brass sextant of sorts (the Antikythera Mechanism, below right) was found in 1901 proving celestial calculations with an instrument was possible two thousand years ago. Little Kythera as of this writing has 44 permanent residents.

Antikythera Mechanism

Incidentally, the ferry in season, see photos below, lands twice a week at Little Kythera doing the nautical equivalent of a “touch and go.” The football-field-long ferry backs up to the dock, lowering the gang way as it backs up. The very moment the gang way is over the dock it drops. All things going off or on do so in about a minute. The gang way lifts a few inches and the ferry leaves immediately, cranking the gang way up the rest of the way while over open water. The docking, exchange, and departure takes less than five minutes.

From Little Kythera you can see Crete to the south and Kythera to the north, taller but farther away. And Kythera is indeed shaped like a lute or a guitar. A large island, it has some 3,000 permanent residents plus an airport. Interestingly, some 100,000 Greeks in Australia claim ancestry to Kythera and try to return at least once a year, in the Greek summer, which is conveniently the Australian winter.  Kythera is the birth place, so to speak, of Aphrodite. The island was first inhabited by the Minoans and then the Phoenicians, both of whom wanted the Murex, a tiny shell fish whose minute anal gland was the only source of royal purple dye in ancient times. How they discovered that is anyone guess.  From Kythera one can see Little Kythera to the south and to the north the southern tip of the main land called Peloponneus, specifically “The Mani” from where we get the word “maniacs” in English because of how tenaciously they fought. It is one area of Greece never occupied by the Turks or the Germans.

If you take the day-long ferry from Crete it lands at Little Kythera, Kythera, then on the mainland at the little city of Gythio, whose sole industry in the past was collecting the royal purple as well… there’s about 10 square feet of ruins there right beside the road.  Gythio was also the home port of the Spartans and the area where this writer’s family comes from.

Ripe fiddlewood berries are black-ish

Now which came first, the instrument then the naming of the island or the island and the naming of the instrument is a debate. But, kythera …kythera…came to mean lyre and from kythara we got guitar and from that we got the fiddlewood tree. How? When Linnaeus was naming plants the English words “violin” or “fiddle” were not common in his time plus he preferred classical names. He knew the wood was used to make musical instruments so he named it  “guitar wood shrub” Citharexylum fruticosum. That got stretched into Guitar Tree and then Fiddlewood Tree. Now you know.

The most common name for the tree in the Caribbean islands is “old woman’s blisters” read it’s used for a lot of ailments. Boiled twigs and decoctions are used if you’re chilled. When mixed with Strongback and Spoonbush it is used for sores. Boiled with mahogany, lignum vitae, Doctor Club roots, Snowberry and papaya latex, it was used to aid indigestion… or perhaps create it…. Also beware… insects of all sorts love the tree so you will encounter them, in numbers. The fruit plup is edible but not prized. Do not eat the seeds.

Green Deane’s “Itemized” Plant Profile: Fiddlewood Tree

IDENTIFICTION: Citharexylum fruticosum: Shrub or tree to 30 feet, short trunk or several trunks, erect branches, compact. Leaves opposite, oblong to oval, with pointed or notched tip, to six inches long, glossy, yellow-green leathery, with orange stalks. Flowers white, tubular, five lobed, 1/8 inch wide, fragrant, in hairy clusters to six inches long. Fruit half-inch wide, brown or orange red when unripe, purple black when ripe. Sweet, two seeds.

TIME OF YEAR: All year

ENVIRONMENT: Coastal pine lands and hammocks

METHOD OF PREPARATION: Ripe fruit edible raw, but not great.  Do not eat the seeds.

Backing up to the dock at Little Kythera

Right, backing up to the dock at Little Kythera, Greece. The ferry comes by twice a week in season, south to Crete one day, north to the mainland the next. Below left is Kythera showing the “neck” of the guitar.  The large picture is the small city of Gythio, home port of the Spartans and of this writer’s ancestors in the villages of Karea to the southwest and Konakia to the northwest.  A small island just a few hundred feet off to the left of Gythio was where Paris and Helen spent the night consummating their love, starting the Trojan War, or so the romantic story goes.

Wild Ficus: Who Gives An Edible Fig?

It’s only 90 miles to the east, and 117 to the west, but the Strangler Fig and Banyan trees will grow farther south and on each coast but not here in Central Florida. One is a native, and one came from India, but they’re cousins none the less, figs as it were, and in the greater Mulberry family. You didn’t know figs and mulberries were related? You do now.

Strangler Fig

The trees take over in similar ways. The Strangler Fig often starts as an epiphyte, a seed “deposited” by a bird in the top of a tree. The fig sends a root down to find earth. Once it does It slowly takes over the tree, enveloping it, sending down more roots. In time it becomes a huge tree. Usually the original victim simply dies and disappears.

The Banyan “walks.” The first time you see one you are amazed. The horizontal branches send down vertical “prop” roots that grow into trunks. The tree simply keeps growing out and down, covering acres. Nearly everything under its shade dies.

The Florida fig is Ficus aurea, FYI-kuss AR-ree-ah, or FEEK-uss AW-ree-ah, Ficus is an old Latin name for the tree or fruit and probably comes from the older Greek word for fig, Siga (SEE-gah and earlier sykon.)  Aurea means golden, referring to the figs’ color when ripe. The Miccosukee and Creeks indians called the tree a phrase that gets translated into the “sticks to you” perhaps a reference to the latex sap. They ate the ripe fruit, used the stems for arrows, made bowstring and netting out of the bark of the roots. They used latex to treat wounds. That latex can also be used to curdle milk for cheese making. The Indians also used the dried latex like gum.

One Banyan Tree

The Banyan tree is also a fig, now called Ficus benghalensis (ben-gal-EN-sis) meaning from Bengal. The largest is in India and covers four acres. It has a circumference of about a half a mile, is some 80 feet high and has (as of 2008) 2880 aerial roots reaching down to the ground. It is said it can shelter 2,000 people.

The reddish fruit of the Banyan tree is not toxic per se but they are barely edible, the worst of famine food. While its leaves are said to be edible, they are more often used as plates and for wrapping food. Fig leaves are also used to impart flavor to fire cooked foods. Some fig leaves in some areas are cooked and eaten. There is only one original reference to  the leaves of the F. benghalensis as being edible so I would view it as suspect. I would want more independent confirmation before I tried to eat one. But, I would cook with it and wrap with it.  The Banyans grow in the warmer areas of the United States including Florida, Texas, Arizona and Southern California.

A third fig in Florida is the Shortleaf Fig or Ficus citrifloia. As its name implies it has leaves similar to citrus trees. The one-inch fruit goes from yellow to dark red when ripe. It is edible but not prime — tasteless actually — and is not improved by cooking.

On a personal note, I have a fig tree in my front yard that is at least 80 years old, and probably much more, from the Azores. Of course, the fig would not be allowed in the United States now but it got here when folks weren’t concerned about such things. The grandfather of a friend married a Portuguese woman back in the 1930s. She was from the Boston area but her family was directly from the Azores, Portuguese being their first language as in my family Greek was. Either she or her relatives brought a cutting from a fig tree in the Azores to Florida via Boston and planted it next to their house in DeLand, Florida. Some 70 years later the original slip, now an aging tree, was losing a battle with dry rot so I took several slips off the tree and got them to root. The tree is gone now but at least four of those slips are still growing and are now trees themselves. They grow big green figs similar to the Kalamata figs of my ancestral home, the Mani, in Greece. That tree, or it clones, has been in the presence of a lot of human life. How old was it on the Azores before a slip was taken? We’ll never know. That slip endured several thousand miles at sea and then a slow 1,200 mile drive down the east coast of the United States. It grew next to the house where Vern Gifford raised two kids, saw numerous grandchildren and went quickly while in his 90s. And the tree lives on.

Also edible: Ficus auriculata, fruits;  Ficus benjamina, ripe fruit; Ficus carica, ripe fruit; Ficus capensis, fruit, young aerial shoots eaten as a vegetable, bark is chewed with cola nuts to alleviate thirst; Ficus elastica, fruit and young leaf shoots cooked. This is the infamous “rubber plant” in home and offices around the world; Ficus glomerata, young shoots cooked, Ficus hirta, very young top shoot eaten raw, ripe fruit edible; Ficus insipida, fruit sometimes good to eat; Ficus lacor, young shoots and sour leaves eaten raw or cooked. Fruit also edible; Ficus laevigata, ripe fruit; Ficus palmata, fruit edible, unripe figs and leafy young shoots boiled and fried and used as a green vegetable; Ficus pseudoplama, young leaves are eaten raw in salads or cooked as a potherb. Fruits also edible; Ficus pumila, ripe fruit; Ficus racemosa, ripe fruit edible, unripe fruits pickled, young shoots eaten raw or cooked; and, Ficus sycomorus, fruit edible, leaves eaten in soups.

Two factoids: Figs are pollinated by a wasp that crawls into the developing fruit. Its “blossoms” all face inward. And the fig tree, called “sycamore” in the Bible, was a common wood for caskets back then. It is the most common ancient casket wood found today.

Green Deane’s “Itemized” Plant Profile

IDENTIFICATION: Strangler fig:  Tree to 65 feet, milky sap, orange twigs, smooth gray or light brown bark, flaking, many aeriel roots. Leaves alternate, stalked, oblong, oval or elliptic, pointed or wedge shaped, two to five inches long, leathery, dark glossy above, paler below. Fruit stalkless, yellow when unripe, dark red when ripe, about one   half inch wide.

TIME OF YEAR: All year

ENVIRONMENT: Hammocks, pine lands, old residential areas

METHOD OF PREPARATION: Raw fruit out of hand. Latex as chewing gum. Banyan leaves can be used as plates and to wrap food.

Caryota: Fishy Toxic Palms

Often the botanical name of a species tells you nothing about the plant. Magnolia comes to mind. It’s a person’s name. However “urens” does enlighten, Caryota urens specifically.

Multi-trunk fishtail palm

Caryota urens is the Fishtail Palm, so called because the bi-pinnated leaves resemble the back end of a fish.  Urens means “stinging” and the fruit does contain a chemical that does sting. That said, the kernel of the fruit is edible but it has to be cleaned completely of the stinging outer flesh.

One of the odd thing about the genus is when it fruits the trunk the fruit is on dies. The single trunk Caryota urens grows fast and lives to between 20 and 25 years old but when it fruits, that’s the end of it, though it can take years to die. The multi-trunk species, Caryota mitis does better and grows a source of more trunks. But, they too die, fruiting from the top down.

As a forager I am used to being told this or that species is toxic. This was one so-called toxic plant that was true. However, that did not keep natives from using this palm. The primary product of the genus is a sugar substitute called kitul honey or jaggery. The juice from the flowers is boiled in a large wide-mouth vessel making golden syrup. The fruits have raphides of calcium oxalate and are not eaten. The seed kernel is edible, however.

Fish tail looking fronds

The growing tip of the palm is also edible as is the palm heart. The sap can also be fermented. Leaves are used for animal fodder, being 2% protein and 9.3% fiber. The sheathing leaf bases provide a strong fiber for brushes. Wood is used to make spears and used like gutters or pipes to carry water.

There are about 15 species of Fishtail Palm, C. urens is used the most. C. mitis has become an invasive in Florida. The botanical name, Caryota, (kair-ree-OH-tuh) is from Greek and means “nut.” Urens (UR-ens) means burning.  Mitis (MIT-iss or MY-tis) means soft, referring to the sheathing leaf bases particularly found on the smaller species.

 Green Deane’s “Itemized” Plant Profile

Seed pulp is toxic, the kernel is edible

IDENTIFICATION: Fronds resemble fish tails. Inflorescences can grow to 10 feet long emerging at the nodes, from the top of the palm down.

TIME OF YEAR: Fruits after 15 to 25 years then continuously until it dies.

ENVIRONMENT: Prefers rich, moist soil and much sun but can tolerate some shade and dry conditions.

METHOD OF PREPARATION: Sap is boiled into a syrup or fermented into wine or a spirit. The growing tip of C. urens is edible as is the heart and young leaf shoots cooked. The seed kernel of both are also edible but the pulp of the fruit of both is not. The bud of the C. mitis is edible after cooking but remains bitter.

Forsythia

Foraging For Forsythia

If you study the eating habits of North American Indians you learn one thing quite quickly. They weren’t mono-green eaters. What I mean is, they usually didn’t eat just one green species of plant at a time.

Today when we have a meal we often have one green food, say string beans or spinach. That serving comprises the entire green portion of the meal. The Indians simply did not do that. It was a leaf here, a blade there, a shoot from over yonder, all mixed in together. From such meager foraging a meal is made. And while the Forsythia was not on their menu it’s one of those little edible you usually mix in with other things.

For a very common ornamental that has also liberated itself there is nothing about the Forsythia as an edible plant in my entire library, which is now around 100 books plus papers, DVDs et cetera. Yet the blossoms are edible raw, though they can be slightly bitter. They add color to salads and are a cheery garnish. The very young leaves are also edible raw but that’s iffy as they contain some of the glycoside Phillyrin, and it’s debatable just how nasty that is. Very young leaves have also been added to soups. As you can see the key is “very young leaves.” I suspect we know these things because some folks in were very hungry for anything green in the spring after long winters.

William Forsyth 1737-1804

The Forsythia genus is named for the Scottish botanist William Forsyth. He was the royal head gardener and a founding member of the Royal Horticultural Society. He is also credited with (intentionally) building the first English rock garden. As a bit of genealogical history the British entertainer Bruce Forsyth is a descendant of his.

As a native to China the Forsythia was introduced to the rest of the world by fellow scotsman Robert Fortune, below,  a famous/infamous plant hunter. It was Fortune who single-handedly smuggle the plants and know-how to make tea out of China establishing it in India, a bit of botanical espionage from which China has only recently recovered. After 250 years China now leads India in tea production. Fortune, who did not know much Chinese or botany did so disguised as a Chinese peasant. And now you know why the British drink tea. They had wars with China but India was their colony. So they planted tea in a friendly place, or occupied place. Views vary.

Robert Fortune 1812-1880

There are about a dozen species of Forsythia, depending upon who’s counting and if you include at least one hybrid. Most of them are native to eastern Asia but one is native to southeastern Europe. There are also many cultivars including dwarf and compact forms. F. suspensa, the weeping Forsythia, is an important herb in Chinese medicine and has been used for at least three thousand years, perhaps four. Called lian qiao it’s unripe yellow fruit and seeds are ground together. Lian qiao is used internally for chills, fevers, headaches and externally for burns, infections, rashes and the like. Lab tests show the seed to be anti-inflammatory (Rouf et ali 2001 and an anti-oxidant (Schinella et ali 2002.) But a 1991 study of 102 raw pharmaceuticals used in traditional Chinese medicine (Yin X et ali)  suggested lian qiao might be potentially cancer causing, perhaps that glycoside issue again. In 2009 (Wang F.N.,  et ali) found three new glycosides in the F. suspensa bringing the total to nine. Forsythia extracts are used in commercial products treating dandruff, acne, and athlete’s foot … Sticking with just the blossoms in a seasonal salad seems wise.

Like the Eastern Redbud (pink) and the Chickasaw plum (white) the Forsythia blossoms on naked branches before its leaves appear, giving us a seasonal flame of yellow. Each of those species use the massive show of color (and ultraviolet markings) to attract early pollinators. Forsythias are found in most urban areas but they have also escaped cultivation making them quite easy to find in spring. Just look for yellow flowers and no leaves.

Oddly, or perhaps understandably, gardeners have a love/hate relationship with the Forsythia. For two weeks every year it is the darling wherever it grows. Then it is rather boring for 50 weeks.  But that doesn’t deter some people. There is a Forsythia festival every year… the second week in March… in… Forsyth, Georgia, about one hour south of Atlanta. If the weather is bad the festival goes on anyway. Forsythias wait for no one. (And yes, there is a Miss Forsythia pageant.)

 Green Deane’s “Itemized” Plant Profile

IDENTIFICATION: Forsythias have narrow, dark green leaves with a lighter underside, in opposite pairs, the margin is serrated. There are also a large number of variegated and golden leaved varieties. Yellow flowers, four narrow petals at right angles form a short tube. One to three flowers per node.

TIME OF YEAR: Your spring

ENVIRONMENT: Sunny, well-drained soil, may need extra watering in dry spells

METHOD OF PREPARATION: Blossoms raw, or cooked but usually raw, slightly bitter. Very young small leaves raw or cooked. Exercise caution with the leaves.

HERB BLURB

Below is the abstract of a study in its entirety. Perhaps something is lost in the translation, or I am reading it wrong. But, the last sentence seems to say don’t worry about phillyrin or forsythiaside in the tissue of the dog you are about to eat because the dog eliminates them from its system quickly. (No, I am not kidding….)

Pharmacokinetics of phillyrin and forsythiaside following iv administration to Beagle dog. Li YX, Peng C, Zhang RQ, Li X, Jiang XH.

Chengdu University of Traditional Chinese Medicine, Sichuan, China.

Abstract

The objective of the present study was to firstly investigate the in vivo pharmacokinetics of phillyrin and forsythiaside in beagle dog. On I.V. administration, a rapid distribution was observed and followed by a slower elimination for phillyrin and forsythiaside. The mean t(1/2Z) was 49.99, 34.87 and 43.81 min for 0.19, 0.70 and 1.43 mg/kg of phillyrin, and 60.90, 64.30, 57.99 min for 0.62, 1.39 and 5.52 mg/kg of forsythiaside respectively. And the AUC(o-t) increased linearly from 36.51 to 160.22 microg x min/ml of phillyrin and from 50.63 to 681.08 microg x min/ml after the three dosage administrated. In the range of the dose examined, the pharmacokinetics of phillyrin and forsythiaside in beagle dog was based on first order kinetics. Although both drugs were widely distributed to various tissues in the dog, no concerns about extensive binding to tissues that may be consumed by the public should a dog be exposed to phillyrin and forsythiaside according to the rapid elimination.
