Wwi: many people died from infections, showed the need for more antibiotics. By the late 1970s so many antibiotics were available that it was no longer pro table to pursue new antibiotics. By the 1990s, the rst antibiotic resistant bacteria appeared. 50% of all anticancer drugs have a natural product origin. Many cns active drugs are synthetic but based upon natural products. Ethnopharmacology: plants to treat infections, stomach/intestinal ailments, pain, mental disorders, reproductive issues. Bioavailable: represents the amount of the drug that gets to the bloodstream.
