Holarrhena antidysenterica
Also known as Kurchi
Pronounced Kutaj (Kurchi): koo-TUJ (KUR-chee). Holarrhena antidysenterica: hol-uh-REE-nuh an-tee-dis-en-TERR-ih-kuh.
Cool, dry, bitter and astringent: an amoebicidal astringent bowel tonic that clears damp-heat dysentery and firms the hot, weeping, infected, over-loose mucosa of the gut.
Insufficient modern controlled safety data; avoid medicinal or high doses in pregnancy as a precaution unless supervised by a qualified practitioner. Ayurvedic tradition has used Kutaj bark in pregnancy for diarrhea and reports no adverse effects, and this genuine traditional use should be acknowledged; but there are no controlled human safety or teratogenicity studies, and the bark and seed contain potent steroidal alkaloids (conessine and congeners) with central nervous system activity, so the prudent modern course is to avoid medicinal doses in pregnancy without professional supervision. Dysentery or persistent diarrhea in pregnancy should be assessed by a clinician because of the dehydration risk. Source basis: absence of modern controlled pregnancy data (NCCIH general guidance for herbs lacking reliable pregnancy information); conessine pharmacology literature.
Insufficient modern safety data; avoid high doses during breastfeeding as a precaution unless directed by a qualified practitioner. There are no data on transfer of Holarrhena's steroidal alkaloids into breast milk or on effects in the nursing infant. No specific harm is documented, but in the absence of data the prudent course is to avoid medicinal or concentrated seed-alkaloid preparations while nursing. Source basis: absence of modern lactation data; Mills and Bone, Principles and Practice of Phytotherapy (precautionary reasoning for alkaloid-bearing herbs).
Ayurveda has long used small, weight-appropriate doses of Kutaj bark for childhood diarrhea (classical pediatric bark-powder doses in the range of 500 mg to 1.5 g), and the bark is comparatively low in toxicity; but modern pediatric safety data are limited, so use in children only under qualified supervision at reduced doses, prefer the bark over the more alkaloid-rich seed, and avoid concentrated seed-alkaloid preparations. Crucially, dysentery and bloody or high-output diarrhea in children carry a real dehydration risk and warrant medical assessment and rehydration rather than herbal self-treatment. Source basis: classical Ayurvedic pediatric dosing (traditional context); NCCIH general guidance that pediatric safety data for most botanicals are limited.
Kutaj has a long Ayurvedic record as a comparatively safe antidysenteric, and most cautions are functional or dose-related. Its intense bitterness can provoke nausea or vomiting in sensitive people. It is cooling, drying, and astringent, so in excess or in the wrong constitution it can aggravate Vata, dryness, and constipation. The bark and especially the seed are rich in potent steroidal alkaloids (conessine and congeners), and conessine has documented central nervous system activity (a CNS-depressant, sedative histamine H3 antagonist with slow CNS clearance and adrenergic affinity); heroic or prolonged dosing of concentrated seed-alkaloid preparations is therefore inadvisable, and ordinary rather than extreme doses should be used. Modern controlled clinical safety data are limited, so avoid high doses where data are lacking (pregnancy, lactation, young children) and do not rely on it as a substitute for medical care in severe or invasive dysentery.
Cold, deficiency-cold, atonic diarrhea without heat or infection, where a cooling astringent is the wrong direction. Known hypersensitivity to Holarrhena or other Apocynaceae. Pregnancy and lactation at medicinal or high doses, on precautionary grounds of insufficient modern safety data (see safety fields). Severe or invasive dysentery with high fever, marked blood, dehydration, or suspected amoebic liver abscess calls for medical evaluation rather than self-treatment (see refer threshold), particularly in children, the elderly, and pregnancy.
Holarrhena pubescens is widely distributed across India, Southeast Asia, and tropical Africa and is not currently assessed as globally threatened, nor is it a United Plant Savers (North American) species. It is, however, in heavy medicinal demand, and bark harvest can be destructive to the tree, creating local pressure in parts of its Indian range where it is a priority for cultivation. Prefer cultivated bark, or the non-destructive seed harvest, and buy from suppliers who can name a cultivated or sustainably managed source over indiscriminate wild bark stripping.
Not a plant of the biblical Near East and not named in canonical Scripture. Holarrhena antidysenterica is native to the Indian subcontinent, Southeast Asia, and tropical Africa and belongs to the Ayurvedic tradition rather than the Mediterranean-biblical one; it is a cornerstone antidysenteric named in the Charaka Samhita and Sushruta Samhita as Kutaja and remains an official drug of the Ayurvedic Pharmacopoeia of India. Included here as a cross-traditional materia medica entry, honestly sourced to its Ayurvedic and South Asian origin.
