| Abstract: |
| Screw tree (Helicteres isora), or kayu ules in local language, is a medicinal plant that can be found in India and Indonesia. The fruit of this species has been proven to be effective to prevent the increase of blood glucose levels (Venkatesh et al., 2004). Meanwhile, in Indonesia the fruit of the screw tree is an ingredient in traditional medicine, known as ‘jamu’, which is sold commercially. One location in Indonesia where this species can be found is in Soe, South Timor Tengah District, East Nusa Tenggara Province. The distribution of this species is discontinuous; it naturally grows with other species, such as Cassia siamea, Psidium guajava, Leucaena leucochepala, Woodfordia fruticose and Canarium Oleosum as a sapling (Umroni et al., 2015). |
