The antihypertensive effect was also observed in experimental renal hypertensive rats, but not in dogs with renal hypertension, but there was a significant antihypertensive effect on elderly "primary" hypertensive dogs.

High concentrations of magnolia preparations also have a certain inhibitory effect on Candida albicans and influenza viruses. 5.
