Transliteration: rtsi sman
<noun> "Essential medicine(s)". The སྨན་ materia medica of Tibetan medicine are divided into eight categories q.v. for listing. This is one of those categories and refers to a type of medicine which is made by incorporating an essential substance derived from something else. An essential substance is like e.g., ག་བུར་ camphor which is extracted from its source, purified to an essential substance, then incorporated into the medicine.
