Operculina Turpethum Root Extract
Also known as: Operculina turpethum (Linn.) Silva Manso, Turpeth root, Indian jalap, Trivrit, Operculina turpethum
Overview
Operculina turpethum, commonly known as Turpeth root or Indian Jalap, is a perennial climbing plant whose root extract is a traditional herbal remedy in the Unani system of medicine. It is primarily recognized for its use in gastrointestinal, respiratory, and inflammatory conditions. The plant's root contains various bioactive compounds, including glycosides, flavonoids, and resinous substances, which are believed to contribute to its therapeutic effects. Historically, it has been employed as a laxative, anti-inflammatory, antiulcer, and antidiarrheal agent, and for respiratory ailments such as asthma. While preclinical research, including in vitro and animal studies, supports many of its traditional uses, human clinical trials are limited and often involve multi-herb formulations, making it challenging to attribute effects solely to O. turpethum. Large-scale systematic reviews or meta-analyses specifically on this herb are currently lacking.
Benefits
Operculina turpethum has demonstrated several potential benefits, primarily supported by preclinical studies and limited human trials. Its gastrointestinal effects include significant antiulcer activity, observed in rat models where methanolic and hydroalcoholic stem extracts reduced aspirin and pyloric ligation-induced ulcers, comparable to ranitidine. It also exhibits antidiarrheal properties, with ethanolic root extract reducing castor oil-induced diarrhea in mice in a dose-dependent manner, similar to loperamide. For respiratory benefits, a randomized placebo-controlled clinical trial involving a combined herbal formulation (including O. turpethum) showed improvements in respiratory indices, cough severity, and activity restriction in children and adolescents with mild-to-moderate asthma. However, the specific contribution of O. turpethum alone in this multi-herb product is not clear. Additionally, methanolic extracts have shown analgesic and antioxidant effects in animal models, supporting its traditional use for pain and inflammation. Preclinical studies also suggest antidiabetic potential through hypoglycemic effects in diabetic rats, though human data are absent.
How it works
The therapeutic actions of Operculina turpethum are attributed to its diverse phytochemical composition. Its antiulcer and antidiarrheal effects are thought to stem from its ability to modulate gastric acid secretion, enhance mucosal defense mechanisms, and inhibit excessive intestinal motility. The observed antioxidant activity is likely due to the presence of flavonoids and phenolic compounds, which act as free radical scavengers, protecting cells from oxidative damage. Anti-inflammatory and analgesic properties may involve the inhibition of prostaglandin synthesis and the modulation of various inflammatory mediators. In respiratory conditions like asthma, its benefits could be linked to anti-inflammatory and bronchodilatory effects, although the precise molecular pathways and targets involved require further elucidation.
Side effects
Comprehensive human safety data for Operculina turpethum are limited, although animal studies generally report no significant toxicity at therapeutic doses. The single clinical trial involving a combined herbal formulation containing O. turpethum did not document common or serious adverse effects. However, there is a potential for gastrointestinal irritation or pronounced laxative effects, especially when consumed at higher doses. Due to the scarcity of research, drug interactions and contraindications are not well-studied, necessitating caution when used concurrently with other medications, particularly those affecting the gastrointestinal or respiratory systems. Safety in special populations, such as pregnant or lactating individuals, and children outside the studied age range, has not been adequately evaluated, and further research is required to establish its safety profile in these groups.
Dosage
There is no standardized human dosage for Operculina turpethum due to limited clinical research. Preclinical studies in rats have utilized doses of 100 mg/kg body weight for antiulcer effects, but these findings do not directly translate to human dosing. The clinical trial that showed benefits for asthma used a combined herbal tablet containing O. turpethum twice daily, but the exact amount of O. turpethum within this formulation was not specified. Consequently, there is no established maximum safe dose or standardized extract concentration available for human consumption. The efficacy can also be influenced by the form of the extract (e.g., methanolic, hydroalcoholic, ethanolic), which has shown varying effects in animal models. Users should exercise caution and consult a healthcare professional, as clear guidelines for dosage, timing, and formulation are currently lacking.
FAQs
Is O. turpethum effective alone for asthma?
Current clinical evidence for asthma involves multi-herb formulations; the isolated efficacy of O. turpethum alone has not been definitively proven in human trials.
Is it safe for long-term use?
Long-term safety data for O. turpethum are currently lacking. Short-term use in a clinical trial involving a combined formulation was generally well tolerated.
Can it be used for diabetes?
Preclinical studies suggest potential antidiabetic effects, but robust human clinical trials are needed to confirm its efficacy and safety for diabetes management.
What form is best?
Methanolic and hydroalcoholic extracts have shown efficacy in animal models for certain conditions. However, human data are insufficient to recommend a specific form for optimal benefit.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC5628523/ – This article details preclinical studies on Operculina turpethum. It reports that methanolic and hydroalcoholic stem extracts at 100 mg/kg significantly reduced aspirin and pyloric ligation-induced ulcers in rats, comparable to ranitidine. It also notes that an ethanolic root extract showed dose-dependent antidiarrheal effects in mice comparable to loperamide, supporting its traditional gastrointestinal uses.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10252578/ – This source describes a randomized placebo-controlled clinical trial involving 60 children/adolescents with mild-to-moderate asthma. The study found that a combined herbal tablet, including Operculina turpethum, significantly improved respiratory indices, reduced cough severity, and decreased activity restriction compared to placebo after one month. However, the study's limitations include its small sample size and the use of a multi-herb formulation, preventing attribution of effects solely to O. turpethum.
- https://www.ijbcp.com/index.php/ijbcp/article/view/765 – This research indicates that methanolic extracts of Operculina turpethum demonstrated analgesic and antioxidant effects in animal models. These findings provide scientific support for the traditional use of the plant in managing pain and inflammation, suggesting its potential therapeutic properties beyond gastrointestinal applications.
