Range. Temperate Asia. Grows naturally in Myanmar; most abundant in Kachin state.

Uses
Leaf: Used as stimulant. Eaten after consumption of questionable foods to neutralize toxins instantly. They are also eaten immediately after bee stings or bites from venomous snakes and scorpions to prevent the venom from reaching the heart. Pulp from the chewed leaves is applied as a poultice to bites and stings. To promote healing of broken bones, the leaves are eaten rather than applied topically because topical application in the case of broken bones is thought to cause “retraction of bad blood”, pain, and infection. However, for bleeding injuries, a poultice of the masticated leaves is applied in a circle around or directly over the wound to stimulate healing. ­

Toxicity:
Eating the leaves in the absence of need is thought to lead to lethargy and heaviness of the body.
