What we have so far
Brazilian snake venom drops blood pressure by blocking ACE. The first rationally designed drug from a venom, and the ancestor of every -pril on the shelf.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
