Dear Jonathan,

I believe viṣaśāstra, as its name implies, is a general term for toxicology, dealing with things like poisons, venoms, etc. Many medical works have sections on this. The Caraka-saṃhitā called this kaumārabhṛtyakam; the Suśruta called it agadatantra; Vagbhata called it daṃṣṭrā. Yijing, in his survey of Indian Medicine, called it 論惡揭陀藥 (cf. T 54.2125.223b28-23c6).

Some of our illustrious colleagues who deal with that literature can perhaps guide you to more specific sources.

best,
Dan

Dear Friends
My friend Charles Ramble is working on a Tibetan text on poison. It mentions for instance 32 types. I am aware that (no doubt among others) Suśrutasaṁhitā in its Kalpasthāna has much to say about poison, but understandably, not how to make it. There seems to exist a term viṣaśāstra, but more I have not been able to discover. I feel I may have overlooked something rather well known.
I would be delighted both to learn more myself (no, I'm not looking to poison anyone!) and to pass along the information to Charles.

Very best,
Jonathan
