Drugs from Mother-Nature

This is likely an incomplete list, but is definitely a starting point for the sake of record-keeping. For me, drug development can be more interesting than the actual drug itself, especially when the development started from a biological source. And maybe after a quick review, you too will appreciate what scientists have accomplished with a little help from the Earth, and you'll have the heart to say thanks to your "Nature" mother next time you use one of these (or something in the same drug class) --

1. Captopril - Brazilian viper venom
2. Exenatide - Gila monster saliva
3. Lovastatin - Aspergillus fungus (also found in oyster mushrooms and red yeast rice)
4. Quinine - Cinchona bark
5. Aspirin - Willow bark and Meadowsweet herb (salicylic acid)
6. Paclitaxel - Yew tree bark
