Prasarini (Paederia foetida)

TL;DR

Prasarini is Paederia foetida Linn., a foetid climbing shrub of the Rubiaceae family, known in Sanskrit as Prasarani and in English as skunk vine. Traditional records list it for joint complaints, diarrhea, cough and liver disorders. Its evidence base is entirely preclinical: rat studies suggest liver-protective and anti-inflammatory activity, but no human trial has ever been conducted to date.

What it is

Prasarini is Paederia foetida Linn., a member of the Rubiaceae family: an extensive, foul-smelling climber with opposite ovate leaves and pinkish-purple flowers. It is native to temperate and tropical Asia, from India to Japan and Southeast Asia, and is called skunk vine in English, Gandha prasarini in Hindi, and Prasarani in Sanskrit (Soni et al., review, Int J Pharm Sci Res).

The plant contains iridoid glucosides (asperuloside, scandoside, paederoside), β-sitosterol, lupeol, ellagic acid, the alkaloids α- and β-paederine, volatile oil and methyl mercaptan, as well as carotene and vitamin C in the leaves (Soni et al., review).

Traditional use

Ethnobotanical and folk records document prasarini for a wide range of conditions: hepatic disorders, rheumatoid arthritis, constipation, diabetes, coughs, asthma, itches, wounds, stomachache, diarrhea, dysentery, pain, flatulence, body ache, toothache and bone fractures. The leafy plant is also consumed as a vegetable in parts of Indonesia (Soni et al., review). These are traditional and folk-use records, not clinical proof: the human-trial evidence is assessed separately below.

Modern research

The evidence base is entirely preclinical: the sources reviewed report animal and laboratory studies only, with no human trial identified.

Liver protection (animal studies only)

In carbon tetrachloride-injured rats, oral Paederia foetida extract for three weeks lowered hepatic lipid peroxidation by about 40% and significantly reduced the toxin-elevated serum enzymes GPT, GOT and ALP, plus bilirubin (Soni et al., review, summarizing the primary study). A 2025 rat study similarly found that the extract reduced ALP, ALT, AST, creatinine and bilirubin in paracetamol-induced liver injury, while lowering inflammatory cytokines (TNF-α, IL-1β, IL-6) and altering Nrf2/HO-1 antioxidant-pathway signaling (Feng & Li, Acta Cir Bras 2025). These animal results do not establish liver-protective effects in people.

The butanol fraction of the leaf extract significantly inhibited granulation tissue formation in cotton-pellet-implanted rats, a standard model of chronic inflammation, and also reduced serum orosomucoid, leading the researchers to suggest possible disease-modifying antirheumatic activity. It did not act through stimulation of the adrenal-pituitary axis (Soni et al., review). This is suggestive animal data only.

Gut and other findings (animal studies only)

In mice, a 90% ethanol extract showed antidiarrheal activity in castor oil and magnesium sulfate models, reducing the purging index dose-dependently at 100–500 mg/kg (Soni et al., review). Rat studies also reported anti-ulcer activity of the roots (possibly via H2-receptor-related inhibition of gastric acid secretion) and glucose-lowering activity of stem extract in glucose-loaded mice at 50–500 mg/kg. An ethanolic extract at 200 mg/kg suppressed cough in conscious cats comparably to the antitussive dropropizine (Soni et al., review). All are animal findings, not human evidence.

Safety

No toxicology data for prasarini were located in the sources reviewed, and no human adverse-event data exist. The fact that the leaves are eaten as a vegetable in parts of Indonesia indicates food-level consumption, not medicinal-dose safety (Soni et al., review). As with any herb taken in medicinal doses, avoid use in pregnancy and breastfeeding unless a qualified clinician advises otherwise.

FAQs

What is prasarini?

Prasarini is Paederia foetida Linn., a foul-smelling climbing plant of the Rubiaceae family, native to Asia and known in Sanskrit as Prasarani (Soni et al., review).

What is prasarini traditionally used for?

Traditional and folk records list it for joint complaints and rheumatism, diarrhea, dysentery, cough, asthma, wounds, pain and liver disorders: ethnobotanical reports, not clinical proof (Soni et al., review).

Does prasarini protect the liver?

Two rat studies, one using carbon tetrachloride injury, one using paracetamol injury, found liver-enzyme improvements with the extract (Feng & Li, Acta Cir Bras 2025). No human trial exists, so liver-protective effects in people are unproven.

Does prasarini help joint pain or arthritis?

In rats, a leaf fraction inhibited chronic-inflammation models, which the researchers described as possibly disease-modifying (Soni et al., review). There is no human evidence for joint benefits.

Is prasarini safe?

No toxicology or human adverse-event data were located. It is eaten as a leafy vegetable in parts of Indonesia, but that does not establish medicinal-dose safety (Soni et al., review). Avoid use in pregnancy and breastfeeding unless a clinician advises.

Does prasarini have side effects?

No human safety studies were found, so side effects of prasarini are uncharacterized. The reviewed animal studies did not report toxicity, but absence of reported harm is not evidence of safety. Report any reaction to a clinician and stop use (Sources: Soni et al., review; Feng & Li 2025).
