title: [Elements for the effective evaluation of natural products with possible antihypertensive effects].
abstract: Within the context of experimental pharmacology, some criteria are discussed for estimating the potential of natural products with possible pharmacological activity for the treatment of hypertension. This disorder has great epidemiological impact in Colombia as well as elsewhere. Discovery of these products can be accomplished by use of accessible pharmacological tests such as the following: developing models of arterial hypertension in the laboratory rat, in vitro tests, in vivo tests and microscopic analysis. Suitable protocols associated with these techniques can capture valuable information about possible effects on hypertension during the evaluation phase of a natural product.
