Title: Guazuma ulmifolia
Mutamba’s long history of effective uses in herbal medicine propelled researchers to begin studying its properties and activities in the laboratory (beginning in 1968). It has been the subject of numerous studies since. In the first study published, using various animals (rats, rabbits, guinea pigs, cats and insects), reported that it lowered heart rate and blood pressure, relaxed smooth muscles and stimulated the uterus. Two years later, another researcher reconfirmed the uterine stimulant effects in rats, validating its historical uses as a uterine stimulant and childbirth aid. In eight different studies from 1987 to 2003, various leaf and bark extracts have clinically demonstrated remarkable antibacterial activity in vitro against several disease-causing pathogens, including Bacillus, Staphylococcus, Streptococcus, E. coli, and Neisseria gonorrhea. One of the recent 2003 studies also confirmed its antioxidant effects. In a 1995 in vitro study, mutamba also demonstrated antiviral activity against Herpes simplex type 1.
These studies could certainly explain why mutamba has been used so effectively in herbal medicine systems for many types of gastrointestinal problems, such venereal diseases as gonorrhea and syphilis, and upper respiratory conditions (pneumonia and bronchitis). Subsequent research focusing on particular chemicals found in mutamba documented their ability to interfere with an enzyme process by which bacteria and pathogens replicate. Scientists showed that these chemicals interacted with a cholera toxin-preventing its toxicity and the resultant diarrhea.
