Bunga de Jolo used as nganga is a potential bacteriocide. (photo)
Vetchia merillii, a palm relative of the bunga (Areca catechu) was found to have a unique potency against the bacterium, Bacillus proteus as well as other pathogens causing infection. Direct extract from the seed showed potent inhibition against the test organisms, a feat the control (Penncilium type) failed to show. This explains the usefulness of bunga de jolo as a substitute of bunga (Areca catechu) as nganga in the absence of the latter. Both produce nuts, which are used by older people for mastication with or without the betel leaf and the occasional lime that goes with the preparation.

Common moss is a practical source of antibiotics
The common most often used in its dried form as substrate for orchids has a puzzling characteristic. It resists rotting and does not arbor the breeding of microorganisms that are pathogenic to the orchid. From this observation coupled by the fact that indigenous people use dried moss to cover wounds and skin diseases, led the researches to conduct an experiment on the antibiotic properties of mosses. The results are positive to bacteria causing skin infection, but the range of antibiosis has yet to be determined. The researchers recommend that further studies be conducted on methods of extraction, other than the use of ethanol, in isolating the active principle which is the key to the antibiotic property of mosses.

Antibiotics from papaya seeds
With the increasing resistance of bacteria to the group of Penncilium antibiotics, scientists are looking into more potent antibiotics. Modern antibiotics however, are expensive and are not readily available particularly in the countryside. But natural antibiotics abound in nature. One such source is the ordinary papaya, specifically the native or solo variety. The researchers claim that the papain in papaya has an antibiotic property and the most likely part where the active compound is concentrated is the seeds, which are thrown away for no use except as propagation material. The seed oil is potent against both gram negative and gram positive bacteria, such as Staphylococcus. . This explains why papaya is a health food. Although the oil has also shown anti-fungal effects, the researchers recommend further studies in this aspect. They also recommend further studies in the preparation of the seed oil as antibiotic drop or ointment. (Casas JM, Cadiz RI, Calvelo AM and MC Cremen, UST 202)


Wow. This entry is very informative. This would be very useful for people who prefer alternative antibiotics, than the ones we usually buy from drugstores. Also, this educates the people about the other important use of some plants, that we usually don't mind. - Paola Jenine Alvarez 4CA5 on Practical sources of antibiotics
