The person to show this list to is actually your pharmacist (not pharm tech). Pharmacists go through years of schooling JUST studying medications/ chemicals and their interactions with each other and the human body. If my cousin was in country, I'd ask her, but she's out of contact for the next few months. (She actually focuses on herbal pharmacology, working on classifying antimicrobial properties of native or historical religious and healing ceremonies; for example some incenses have antiviral properties that the drug companies are seeeeeeeriously trying to isolate... but they only work inhaled, only on some viruses, and have some rather serious side effects. It'll be years if not decades before those are on the market).
ANYHOW... Your pharmacist will need to know the chemical composition of horsetail rush (and anything else that doesn't list out what the comp is) and then they'll be able to tell you very easily.
