註釋Man from the earliest times has had an innat desire to find means for ameliorating the stresses of his environment. Oruginally many natural substances such as opium, hyoscyamus, and cannabis were administered with therapeutic intent for their effects on sensation and emotion. Later the synthetic chemist developed a variety of chemically unrelated central nervous system depressants. Although these products and compounds possessed some attributes for alleviating physical pain and mental stress, they unfortunately coud produce effects led to deterioration of the individual and even to physical dependence on the drug. No doubt the calming and hypotensive effects of Rauwolfia have been known for humandreds of years, but it was not until modern scientific methods began to elucidate the actions of depressant drugs that an effect different from sedation or hypnosis was shown to be inherent in certain drugs.
