Certainly, not all herbs are suitable for the preparation of teas, and some plant species may be extremely toxic to humans (e.g., various cultivars of Nerium oleander, which contain cardiac glycosides--oleandrin, oleandroside, nerioside, and digitoxigenin
CBG and other bufanolide steroid compounds have been reported to have similar chemical structures to digitoxigenin
(Figure 1) and to possess both pharmacological and toxicological effects in in vitro and in vivo studies.
Some of these compounds include tubocurarine, morphine, codeine, aspirin, atropine, pilocarpine, ephedrine, vinblastine, vincristine, taxol, podophyllotoxin, camptothecin, digitoxigenin
, gitoxigenin, digoxigenin, capsaicin, allicin, curcumin, and artemisinin.
