Traditional Use:

This plant is used basically for the procurement of abortion. The term peluruh actually refers to the ease of the leaves falling off from the stem on slight jerk. Ridley reports the decoction of the whole plant is used to induce abortion while Burkill reports that Alvin mention the use of a decoction of the roots was used [2][3] 

According to my personal recording of the use of this plants, the Orang Asli of the Chek Wong tribe use the whole plant in a decoction to procure abortion and in combination with other plants to hasten the involution of the uterus. The people from east coast Malaysia (Jerantut) use the whole plant as an ingredient of a pot herb given to women after delivery to induce rapid involution of the uterus. [4] 

No other uses for the plant have been recorded. 

Pre-Clinical Data

Pharmacology

Antifertility activity

The administration of a decoction of the roots of this plant for 10 days post-coitally has caused a reduction in the litter size of rats. In other study, it was shown that individually C. longifolia caused an increase in LH in rats while in combination with other plants the compound medicine cause reduction of the FSH and LH. In another report of similar compound medicine, the oestrogen and progestogen levels were suppressed in non-pregnant and pseudo-pregnant female rats. [5][6]
