Notable Constituents:
- Ascaridole
Bicyclic monoterpenoid used as an anthelmintic drug but with considerable toxicity. It can cause irritation of skin and mucous membranes, nausea, vomiting, constipation, headache, vertigo, tinnitus, temporary deafness and blindness. Prolonged exposure induces depression of the central nervous system and delirium which may become convulsions and coma. Long-term effects include pulmonary oedema, hematuria, albuminuria and jaundice. Fatal doses were reported as one teaspoon of wormseed oil for a 14-month-old baby (at once) and daily administration of 1 mL over three weeks to a 2-year-old child. Ascaridole is also carcinogenic in rats.

Reference Notes:
Individual herb information has sourced mainly from TCM Wiki and American Dragon for basic data and then updated manually with my own notes. Zhou, Xie and Yan (2011): Encyclopedia of Traditional Chinese Medicines, Vol. 5, and A+ Medical Encyclopaedia have been used for entries not available from those sources with additional material searched for and filled in where available. Western herbs not appearing in the Chinese literature have used Ross (2010): Combining Western Herbs and Chinese Medicine: A Clinical Materia Medica, White Rabbit Institute of Healing and therapeutika.ch. Choices of which source to use or combine have been my own.
