Indian Poke, Indian Hellebore, False Hellebore, Green False Hellebore)
Part used.—The rootstock, dug in autumn when the leaves have died down.

Habitat and range.—American false-hellebore is native in rich wet woods, swamps and wet meadows, its range extending from Canada, Alaska, and Minnesota south to Georgia and Tennessee.

In eastern North America, var. viride occurs from southwestern Labrador and southern Quebec south to northern Georgia. In the west, var. eschscholzianum occurs from Alaska and Northwest Territory south through Yukon, British Columbia, Alberta, Washington, Idaho, Montana, and Oregon to northern California.

It is found in wet soils in meadows, sunny streambanks, and open forests, from sea level in the north of the range, up to 1,600 m in the southeast and 2,500 m in the southwest

Description.—The large bright-green leaves of this plant make their way through the ground early in spring, followed later in the season by a stout, erect leafy stem, sometimes growing as tall as 6 feet. It is round and solid, pale green, closely surrounded by the sheathing bases of the leaves and unbranched except in the flowering head. The large leaves, the lower ones of which are from 6 to 12 inches in length and 3 to 6 inches in width, are hairy and pleated like a fan. The numerous greenish-yellow flowers are produced from May to July in rather open clusters. The plant is very poisonous……...CLICK & SEE THE PICTURES

It is extremely toxic, and is considered a pest plant by farmers with livestock. The species has acquired a large number of common names within its native range, including American False Hellebore, American White Hellebore, Bear Corn, Big Hellebore, Corn Lily, Devils Bite, Duck Retten, Indian Hellebore, Itch-weed, Itchweed, Poor Annie, Blue Hellebore, and Tickleweed.

It is a herbaceous perennial plant reaching 0.7–2 m tall, with a solid green stem. The leaves are spirally arranged, 10–35 cm long and 5–20 cm broad, elliptic to broad lanceolate ending in a short point, heavily ribbed and hairy on the underside. The flowers are numerous, produced in a large branched inflorescence 30–70 cm tall; each flower is 5–12 mm long, with six green to yellow-green tepals. The fruit is a capsule 1.5–3 cm long, which splits into three sections at maturity to release the numerous flat 8–10 mm diameter seeds. The plant reproduces through rhizome growth as well as seeds.

There are two varieties:
Veratrum viride var. viride. Eastern North America. Side branches of inflorescence erect or spreading.
Veratrum viride var. eschscholzianum (Roemer & Schultes) Breitung. Western North America. Side branches of inflorescence drooping.

The related western North American Veratrum californicum (White False Hellebore, Corn Lily) can be distinguished from sympatric var. eschscholzianum by its whiter flowers, with erect side branches of the inflorescence

Medicinal uses:
The plant is highly toxic, causing nausea and vomiting. If the poison is not evacuated, cold sweat and vertigo appears. Respiration slows, cardiac rhythm and blood pressure falls, eventually leading to death.

It is used externally by several Native American nations. Although is rarely ever used in modern herbalism due to its concentration of various alkaloids, it has been used in the past against high blood pressure and rapid heartbeat; a standardized extract of V. viride alkaloids known as alkavervir was used in the 1950s and 1960s as an antihypertensive.  The root contains even higher concentrations than the aerial parts.

Any use of this plant, especially internal use, should be carried out with great care and preferably only under the supervision of a qualified practitioner.  A decoction of the root has been used in the treatment of venereal disease. The roots have been grated then chewed and the juice swallowed as a treatment for colds. A poultice of the mashed raw root has been used as a treatment for rheumatism, boils, sores, cuts, swellings and burns. The dried and ground up root has been used as a dressing on bruises and sores. A poultice of the chewed root has been applied to rattlesnake bites to draw out the poison. The powdered root has been rubbed on the face to allay the pain of toothache.  A decoction of the root has been taken orally by both men and women as a contraceptive. A dose of one teaspoon of this decoction three times a day for three weeks is said to ensure permanent sterility in women.

The plant was used by some tribes to elect a new leader. All the candidates would eat the root, and the last to start vomiting would become the new leader.

Indian Podophyllum

Botanical Name: Podophyllum hexandrum
Family: Berberidaceae
Genus: Podophyllum
Species: P. hexandrum
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Ranunculales

Synonyms : Podophyllum   emodi.

Common Name : Himalayan mayapple or Indian may apple

Indian Name: Papri or Banbaigan

Habitat :  Indian Podophyllum  is native to E. Asia – Afghanistan to China. It grows on   the scrub forests and alpine meadows, usually in humus rich soils, 2000 – 3500 metres in the Himalayas. Very abundant in fir forests in Kashmir.

Description and Composition
Indian Podophyllum is an erect, succulent herb with a creeping root stalk. It has flower-bearing erect branches leafy at top. The plant has toothed, purple spotted leaves, deeply divided in 3 to 5 lobes. The flowers are white or pinkish, cup-shaped and solitary. Its fruit is egg-shaped and scarlet in colour. The dried rhizomes of the plant constitute the drug.

The perennial herb Podophyllum hexandrum (syn. P. emodi), bearing the common names Himalayan mayapple or Indian may apple, is native to the lower elevations in and surrounding the Himalaya. It is low to the ground with glossy green, drooping, lobed leaves on its few stiff branches, and it bears a pale pink flower and bright red-orange bulbous fruit. The ornamental appearance of the plant make it a desirable addition to woodland-type gardens. It can be propagated by seed or by dividing the rhizome. It is very tolerant of cold temperatures, as would be expected of a Himalayan plant, but it is not tolerant of dry conditions.

The plant is poisonous but when processed has medicinal properties. The rhizome of the plant contains a resin, known generally and commercially as Indian Podophyllum Resin, which can be processed to extract podophyllotoxin, or podophyllin, a neurotoxin. It has been historically used as an intestinal purgative and emetic, salve for infected and necrotic wounds, and inhibitor of tumor growth. The North American variant of this Asian plant contains a lower concentration of the toxin but has been more extensively studied.

The active principle of Podophyllum is contained in the resinous mixture known as podophyllin. The other constituent of the root is podophyllotoxin. The rhizomes yield podophyllol, a sticky resin, quercetin and podophyllotoxin.

According to Viehoever and Mack (1938), the only active crystallisable substance isolated from either podophyllum or podophyllin is podophyllotoxin. Probably, it is not the chief cathartic principle, which is still to be isolated.

Podophyllum Emodi (Indian Podophyllum), a native of Northern India. The roots are much stouter, more knotty, and about twice as strong as the American. It is not identical with, nor should it be substituted for, the American rhizome. It contains twice as much podophyllotoxin, and in other respects exhibits differences. Indian podophyllum is official in India and the Eastern Colonies, where it is used in place of ordinary podophyllum.

Cultivation :    

Prefers a moist peaty soil and filtered light or shade. Grows well in a moist open woodland. Hardy to about -20°c, it takes some years to become established but is very long lived in a suitable habitat. Young leaves may be damaged by late frosts but otherwise the plants are quite hardy. Over collection of the plant from the wild is becomimg a cause for concern as local populations are being endangered. Young plants only produce one leaf each year, older plants have 2 or 3 leaves each year. Plants in this genus have excited quite a lot of interest for the compounds found in their roots which have been shown to have anti-cancer activity. There are various research projects under way (as of 1990). The sub-species P. hexandrum chinense. Wall. has larger flowers and more deeply divided leaves.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame. Sow stored seed in a cold frame in early spring. The seed germinates in 1 – 4 months at 15°c. Prick out the seedlings into individual pots when they are large enough to handle and grow on in a shady part of the greenhouse for at least 2 growing seasons. Plant them out into their permanent positions in the winter when the plants are dormant. Division in March/April

Edible Uses:     Fruit  is eaten raw. It must only be eaten when it is fully ripe. Juicy but insipid. The fruit is about 5cm long. The leaves are edible according to one report but this must be treated with some caution, see notes on toxicity above

Constituents.  ”The chief constituents of Indian podophyllum are podophyllotoxin (2 to 5 per cent.) and podophylloresin (compare Podophylli Rhizoma). The drug yields from 6 to 12 per cent. of podophyllin when treated in the same way as the American rhizome, but the podophyllin so obtained is not identical with, nor should it be substituted for, that from the American drug, since it contains approximately twice as much podophyllotoxin, and in other respects exhibits differences (compare Podophylli Rhizoma).

Action and Uses. Indian podophyllum rhizome is official in India and the Eastern Colonies, where it is used in place of ordinary podophyllum; it is stated to be twice as active as the latter.

Healing Power and Curative Properties
The herb Podophyllum is used as a hepatic stimulant and as an agent to promote the flow of bile. It is also useful as a purgative and as a drug to correct disordered processes of nutrition and to restore the normal function of the system. It is a bitter tonic which helps induce vomiting.

Chronic Constipation
The drug is highly beneficial for treating chronic constipation and is used as a purgative. The safe single dose is 0.01 gm. Its action is slow but strong. In large doses, it can cause acute irritation and griping. It should therefore be administered either in combination with belladonna or Indian aloe.

Skin Disorders
Podophyllum is reported to be useful in many skin diseases and tumorous growths. It has acquired importance in recent years for its possible use in controlling skin cancer.

Other Uses:  A medicinal resin is obtained from the plant. It is extracted with alcohol

Precautions:
Podophyllin greatly irritates the eyes and the mucous membranes. The resin does not affect normal skin but may be absorbed by irritated or abrased skin and helps purging. It is an effective purgative, but in toxic or over doses it produces intense enteritis or inflammation of the small intestines which may sometimes result in death.
