The root is said to serve the Russians for ginger ; and the whole 
- herb abounds with a white, bitter, fetid juice, of the consistence 
of cream, which soon dries to a brown acrid resin. The milky 
exudation is the only character by which Tournefort distinguishes 
his Thyoselinum from his Oreoselinum.
