Antimicrobial activity of different part of plant extracts of wild yam (Dioscorea hispida Dennst)
Traditionally, the use of plants and herbs can give the significant benefits for the healing process to cure for the human disease. There are some of the yam species that known as intoxicating yam species that grows well in Malaysia included Ubi Gadong (Dioscorea hispida Dennst). Thus, these plants...
