Botany
Payang-payang is an erect undershrub, 0.5 to 1.5 meters in height. Leaves are 3-foliate. Leaflets are finely hairy beneath, the terminal one being oblong, 8 to 13 centimeters long, and more than twice as large as the two lateral ones. Inflorescence is terminal and axillary, and 8 to 25 centimeters long. Flowers are white and about 6 millimeters long, umbellate or fascicled, hidden by the distichous, orbicular bracts, which are 1 to 1.5 centimeters in diameter. Stamens are 10, upper one free, other 9 united. Ovary is few- to many-ovuled, superior. Fruits are pods, oblong, hairy and usually of 2, rarely 1- or 3 joints.

Parts utilized 
Roots, bark, flowers and leaves.
Collect leaves from May to October, roots the whole year round.
Rinse, cut into sections or pieces, sun-dry.

Properties
Tart and cooling.
Considered anthelminthic, antipyretic and anticontusion.

Constituents
– Study yielded a new glycoside, the 1-glucosylrhamnoside of physcion from the seeds of D pulchellum.
– Contains tryptamines.
– Roots yield betulin, a-amyrin, and ß-sitosterol.
– Study yielded fifteen simple indolic bases (I-XV) with three broad structural types, viz., indole-3-alkylamine, ß-carboline, and tetrahydro-ß-carboline. Fruits showed the major accumulation of Nb-oxides while the roots localized the quarternary bases.

Study Findings
• Pharmacologic effects: Effects of the extract from Desmodium pulchellum in rats – Study of extracts on mice showed major effects on motor, respiratory and cardiovascular systems. The bark extract showed to be most potent.
• Alkaloid Effects on Collagen: Study showed the total alkaloid of Desmodium pulchellum could restrain collagen protein I, III, IV and synthesis of TGF ß1 for hepatic fibrosis in mouse liver.
• DMT: Many of the psychedelic plants contain dimethyltrptamine. Desmodium pulchellum contains 0.2%
5-MeO-DMT, small quantities of DMT. DMT dominates in seedlings and young plants, while 5-MeO-DMT dominates in mature plant (whole plant, roots, stems, leaves, flowers).
• Anthelmintic: Study on effects of D. pulchellum’s root extract showed the herb may have an antihelmintic effect on the fluke Opisthorchis viverrini in hamsters.
• Behavioral Effects: Study of extract of D. pulchellum in mice showed an activity mediated via the serotonergic system and suggested a potential for the extract as a useful antidepressant.
• Anti-Hepatofibrotic: Study showed Desmodium pulchellum extract has anti-hepatic fibrotic effects on rats with hepatic fibrosis induced by CCl4. The mechanism may be through increasing the liver cell immunity against injury and indirectly reducing the formation of liver collagen protein.
• Anti-Diarrheal / Leaf Extract: Study evaluated a methanol and petroleum ether extract for activity against castor oil-induced diarrhea and enteropooling and intestinal motility in rats. Results showed significant reduction of diarrheal severity and significant reduction of intestinal volume. Both fractions showed active ingredients, but the ethanol fraction showed better potential.
