What is Kutaj?
Kutaj (Holarrhena antidysenterica), known in Sanskrit as Kutaja (कुटज), is a medicinal tree native to tropical India and Southeast Asia, renowned in Ayurveda as the pre-eminent herb for treating diarrhea, dysentery, and gastrointestinal infections. The name Kutaja means “born in the mountains” (Kuta = mountain, ja = born), reflecting its natural Himalayan and mountainous forest habitat. All parts of the Kutaj tree — bark, seeds, flowers, and leaves — possess powerful astringent, antibacterial, and digestive properties.

Health Benefits of Kutaj
- Diarrhea and Dysentery Treatment
Kutaj is Ayurveda’s most celebrated antidiarrheal herb (Atisarghna). Its bark and seeds (Indrayava) contain conessine and kurchicine alkaloids that exhibit powerful activity against Entamoeba histolytica and other diarrhea-causing organisms. It effectively treats acute and chronic diarrhea, amoebic dysentery, and bloody stools. - Gastrointestinal Infection Management
The broad-spectrum antimicrobial properties of Kutaj make it effective against bacterial, amoebic, and fungal gastrointestinal infections. It is used in formulations for gastroenteritis, intestinal infections, and IBS with infective components, reducing both the causative organisms and the inflammatory response. - Irritable Bowel Syndrome (IBS) Support
Kutaj’s combination of astringent, anti-inflammatory, and digestive-toning properties makes it valuable for managing IBS. It reduces intestinal hypermotility, soothes inflamed intestinal mucosa, and helps establish regular bowel habits in individuals with alternating diarrhea and constipation patterns. - Digestive Health and Appetite Improvement
The bitter taste and Deepana (appetiser) quality of Kutaj stimulate digestive fire (Agni), improve appetite, and reduce the feeling of heaviness and bloating after meals. It is used in Ayurvedic formulations for Agnimandya (weak digestion) and Ama (toxic accumulation) conditions. - Liver Health and Anti-inflammatory Action
Kutaj supports liver function through its anti-inflammatory and hepatoprotective compounds. It reduces hepatic inflammation, supports bile production, and is used in formulations addressing liver congestion, hepatitis, and conditions where liver weakness contributes to digestive disorders. - Skin Infections and Wound Healing
The antimicrobial and astringent properties of Kutaj bark are utilised topically for skin infections, boils, abscesses, and chronic wounds. Its cooling potency reduces inflammation and its antibacterial action prevents infection in compromised skin conditions. - Haemorrhoids with Diarrhea
Kutaj is specifically indicated in Arsha (haemorrhoids) complicated by diarrhea — a combination called Atisar-Arsha in classical texts. Its astringent and anti-inflammatory properties address both the diarrhea and the inflammation/bleeding of haemorrhoids simultaneously.
How to Use Kutaj
| Form | Dosage | How to Take |
|---|---|---|
| Bark Powder (Churna) | 3–5 g | With buttermilk or warm water 2–3 times daily for diarrhea, dysentery, and IBS |
| Seed Powder (Indrayava Churna) | 1–3 g | With warm water or honey for amoebic dysentery and gastrointestinal infections |
| Decoction (Kwatha) | 50–100 ml | Twice daily for digestive infections, liver support, and inflammatory bowel conditions |
| Classical Formulation (Kutajarishta) | 15–30 ml | Diluted with equal water after meals; excellent for chronic diarrhea, IBS, and haemorrhoids |
Side Effects & Precautions
Kutaj is generally safe when used in therapeutic doses under supervision. It should be avoided in cases of liver disease, kidney disease, and gastrointestinal ulcers, as its strong astringent and bitter properties may worsen these conditions. Pregnant women should avoid large doses of Kutaj as it may stimulate uterine contractions. The conessine alkaloid in Kutaj seeds can be toxic in high doses, causing dizziness and neurological symptoms — always use under qualified professional guidance. Individuals on hepatic or renal medications should inform their practitioner before using Kutaj preparations.
Classical References
Kutaja is one of the most frequently cited herbs in classical Ayurvedic texts. Charaka Samhita (Chikitsasthana) devotes an entire chapter (Atisara Chikitsa) where Kutaja is described as the primary remedy for all types of diarrhea. Sushruta Samhita includes it in formulations for dysentery, haemorrhoids, and skin conditions. The Ashtanga Hridayam recommends Kutaja for Pitta-Kapha disorders of the digestive tract. It is the main ingredient in the classical fermented formulation Kutajarishta and features in Kutaja Ghan Vati — both widely used to this day in Ayurvedic clinical practice.

Kutaj’s long history as a digestive-tract herb finds a complementary practice in yoga postures like Pawanmuktasana and gentle seated twists, traditionally used to ease bloating and support gut motility. A calmer nervous system, cultivated through regular practice, can also reduce the stress that often aggravates digestive symptoms. Habuild’s free yoga challenge offers guided sessions to help build that gut-supportive rhythm.
