“…Grown in a range of ecological zones in Africa and the Arabian Peninsula (Bonsi et al, 1995), the plant is commonly referred to as bitter leaf. Locally, it is called "omubirizi" or "omululuza" (West and Central Uganda); "olusia" (Luo, Kenya); or "ewuro", "etidot" and "olugbo" (Southern Nigeria).…”

Vernonia amygdalina is commonly used for food and health purposes. Processing of the leaf for food is aimed at removing bitter tasting antinutritional principles like saponins. This study was designed to determine the antipyretic and antinociceptive property of the crude saponin from Vernonia amygdalina leaf. Standard procedure for antipyretic study using Saccharomyces cerevisiae induced pyrexia in rats; and acetic acid induced writhe, hot plate and cold tail flick tests for antinociceptive study in mice were used. Data for the crude saponin showed significant (P ≤ 0.05) dose dependent anal temperature decrease. The antinociceptive data in mice was significant (P ≤ 0.05) in the writhing test contrary to the cold tail flick test. In acute toxicity study, an LD 50 of 5.1523 g/kg using oral route indicated it was practically non-toxic. Finding suggests that Vernonia amygdalina leaf prepared as diet could be of potential benefit to ailing persons with fever and/or pains, if processing technique adopts minimal loss of principles like saponins.

“…Locally, it is called "omubirizi" or "omululuza" (West and Central Uganda); "olusia" (Luo, Kenya); or "ewuro", "etidot" and "olugbo" (Southern Nigeria). In Southern Ethiopia, dairy farmers feed the boiled leaves to their stock during the dry period, and also to broilers as diet substitute (Bonsi et al, 1995).…”

“…The leaves are green with characteristic odour and bitter taste (Bonsi et al, 1995a). V. amygdalina is a valuable medical plant that is widespread in East and West Africa (Burkill, 1985), it is known as bitter leaf, due to its characteristic bitter taste and flavour, and may be used as an active anticancer (Izevbigie, 2003), antibacterial, antimalaria and antiparasitic agent (Tadesse et al, 1993).…”

The aqueous ethanol and acetone-ethanolic extracts of Vernonia amygdalina leaves and stems were investigated for their antimicrobial activities compared to ciprofloxacin, against Escherichia coli, Klebsiella sp and Staphylococcus sp. The antimicrobial activity of each extract on the isolates was determined by agar well diffusion and minimum inhibitory concentration methods. The acetoneethanolic extract of the leaf showed the highest antibacterial activity on Klebsiella sp in both methods used, followed by the ethanol leaf extracts on the same organism. E. coli and Staphylococcus sp were not susceptible to any of the extracts even at higher concentrations. The aqueous extracts of both leaf and stem were ineffective on all the test isolates at all concentration. Comparatively, the test isolates were sensitive to ciprofloxacin in both methods used but the antibacterial effect of acetone-ethanolic leaf extract on Klebsiella sp was higher than that of ciprofloxacin on Klebsiella sp. The results from this research showed that V. amygdalina could be used as raw material in the synthesis of antimicrobial drugs, especially against Klebsiella sp which have been attributed with high level drug resistance in urinary tract infections.

“…It is propagated vegetatively while growing under a range of ecological zones in Africa and produces large mass of forage and is drought tolerant (Bonsi et al, 1995). Although the leaves are used for human consumption, its production outweighs its human consumption suggesting that the excess may be utilized as feed for ruminants without detrimental effects on general productivity of animals.…”
