Cleome viscosa, known in Thai as “ผักเสี้ยนผี,” sits quietly in many Thai homes and markets. Once just a pungent weed in backyards, it has become a focal point for researchers exploring how local wisdom can inform modern health, especially in health, education, culture, and tourism contexts.
The plant remains deeply rooted in daily Thai life. Leaves, seeds, and stems are used in simple remedies and everyday foods. Traditional practices include fermenting the leaves as a side dish to aid digestion and cooling the body. Folk healers across regions describe its role in reducing fevers, easing muscle pains, and treating minor wounds, often alongside narratives about boosting vitality. As Thailand weighs global health trends, Cleome viscosa invites curiosity about what local knowledge may contribute to contemporary science.
Beyond Thailand, Cleome viscosa has a long-standing reputation in Southeast Asia and parts of India for its medicinal properties. Communities have used it as an effective remedy against intestinal worms, a carminative to ease gas, an antiseptic for wounds, and a febrifuge to lower fever. In rural settings, collecting the plant during the rainy season is a community exercise, reinforcing its place in both cuisine and healing.
Modern science is beginning to explore these traditional claims. Reviews of ethnobotany and pharmacology highlight compounds in Cleome viscosa, including flavonoids like quercetin, and monoterpenes such as myrcene. Flavonoids are noted for antioxidant and anti-inflammatory actions, which may help mitigate cellular stress and excessive immune responses. Such findings align with Thai experiences of using the plant for inflammation, fevers, and general discomfort.
Laboratory studies have shown antimicrobial activity in plant extracts, with potential to inhibit bacteria like Staphylococcus aureus and Escherichia coli. Some studies compare these effects to conventional antibiotics, offering scientific context to the plant’s traditional use in wound care and infection control. In addition, researchers have observed anti-inflammatory and analgesic effects in animal models, including reductions in inflammatory markers and decreased pain sensitivity after treatment with extracts.
Immunomodulatory effects have also attracted attention. Evidence suggests Cleome viscosa can influence immune cell activity, potentially supporting the body’s defenses. This resonates with Thai heritage that crafts tonics and remedies intended to strengthen vitality and resilience. Some studies point to possible protective effects on the liver and the stomach, further enriching the discussion about its therapeutic scope.
However, translating traditional use into clinical practice is complex. There is no universally accepted human dosage yet, and as with any botanical remedy, there can be adverse effects. Some reports note mild digestive upset at higher doses, and topical applications can trigger irritation or allergic reactions in sensitive individuals. Thai health professionals emphasize caution and advise consulting trained practitioners before self-medicating, especially for individuals with chronic conditions or those on other medications.
The story of Cleome viscosa illustrates a constructive fusion of heritage and science. Its presence in fermented foods such as “ผักเสี้ยนดอง” connects culinary culture with medicinal potential. This plant’s journey—from community gathering to laboratory investigation—mirrors Thailand’s broader effort to harmonize traditional wisdom with evidence-based medicine. For researchers, policymakers, and travelers interested in natural health, Cleome viscosa offers a case study in responsible exploration of local plants.
Looking ahead, researchers advocate for deeper clinical studies and human trials to clarify safety and efficacy. Such work could position Thailand as a leader in natural health products, linking local biodiversity with growing global interest in plant-based remedies. For everyday readers, the message is clear: Cleome viscosa deserves respect as part of Thailand’s living botanical heritage, with cautious, science-backed exploration guiding future use.
If you are considering Cleome viscosa for traditional or modern purposes, consult a qualified health professional before starting any herbal regimen, especially if you are pregnant, nursing, managing a chronic condition, or taking prescription medications.
