Medicines are either man made or obtained from living organisms like plants, bacteria, animals etc and hence the latter are called natural products. Sometimes natural products are chemically altered by man to reduce toxicity or side effects. Write against each of the following whether they were initially obtained as a natural product or as a synthetic chemical. Vitamin C.............
