Ankol (Sanskrit: अङ्कोल), botanically Alangium salvifolium (L.f.) Wangerin (syn. Alangium lamarckii), belonging to the family Alangiaceae (now classified under Cornaceae), is a medium-sized tree native to tropical India, Sri Lanka, and Southeast Asia. All parts of the plant — root, bark, leaves, fruits, and seeds — have significant medicinal value in Ayurveda. It is classically used for skin diseases, snake and scorpion bites, joint pain, and nervous system disorders. Modern research confirms its alkaloid-rich profile with anti-venom, anti-inflammatory, and anticancer properties.

Health Benefits of Ankol
Anti-Venom and Toxin Management
Ankol’s most distinctive classical indication is Vishahara — neutralizing animal venoms and biological toxins. The root bark is considered a premier remedy for snake and scorpion bites in traditional Indian medicine. Alkaloids including alangimarckine, lamarckine, and cephaeline demonstrate anti-venom activity, potentially inhibiting phospholipase A2 enzymes present in snake venom. Ethnobotanical surveys across India consistently record Ankol root paste being applied to snake bite wounds while a decoction is given internally. (Journal of Ethnopharmacology, 2009)
Skin Diseases and Dermatological Conditions
As Kushtaghna (anti-dermatotic), Ankol is an important herb in Ayurvedic dermatology, addressing conditions from eczema and psoriasis to fungal infections and leprosy (Kushtha). The bitter alkaloids and tannins in the bark have potent antimicrobial and anti-inflammatory effects relevant to chronic skin conditions. Leaf juice and bark paste are applied topically for skin infections, itching, and inflammatory dermatoses. Modern research confirms antibacterial and antifungal activity of bark extracts against common dermatological pathogens.
Anti-inflammatory and Joint Pain Relief
Ankol’s Shothaghna (anti-inflammatory) and Vedanasthapana (analgesic) properties make it effective for arthritis, gout, and musculoskeletal pain. Ethanolic bark extracts significantly reduce carrageenan-induced paw oedema in animal models, demonstrating potent anti-inflammatory activity. The mechanism involves inhibition of COX and LOX pathways. In traditional Ayurvedic practice, the root bark decoction and oil infusions are used for joint conditions, while the leaf paste provides local anti-inflammatory relief.
Nervous System Support and Analgesic Action
The alkaloids in Ankol roots — particularly alangimarckine — have demonstrated significant analgesic and CNS activity. The plant is used in Ayurveda for neurological conditions including paralysis, sciatica, and convulsions. Animal studies show the alkaloid fractions produce significant antinociceptive effects in standard pain models, supporting its traditional use as an analgesic. The plant is also noted in classical texts as a remedy for Vata-driven neurological imbalances. (Phytochemistry, 1987)
Digestive Health and Antiparasitic Action
As Krimighni (antiparasitic) and with its strong bitter-pungent taste, Ankol is used in Ayurveda to eliminate intestinal worms and manage digestive infections. The alkaloids demonstrate in vitro activity against intestinal parasites and pathogenic bacteria. The fruit is used as a natural purgative in folk medicine, while the bark decoction is given for dysentery and chronic diarrhea with infective etiology. Its Deepana-Pachana properties also help correct digestive fire imbalances.
Wound Healing and Antimicrobial Activity
Ankol leaf and bark preparations demonstrate significant wound-healing promotion through their astringent, antimicrobial, and anti-inflammatory properties. Tannins in the bark promote tissue contraction and hemostasis, while alkaloids prevent wound infection. In vitro studies confirm bactericidal activity against Staphylococcus aureus, Streptococcus pyogenes, and various gram-negative pathogens relevant to wound infections. (Asian Pacific Journal of Tropical Medicine, 2010)
Oral Health and Dental Care
Ankol bark is used traditionally as a dental care agent — chewing bark sticks as a natural toothbrush — leveraging its antimicrobial and astringent properties for oral hygiene. The plant’s bactericidal activity against oral pathogens including Streptococcus mutans (a primary cause of dental caries) and its astringent tannins that tone gum tissue make it an effective natural oral care agent. This is consistent with broader Ayurvedic Danta dhavana (tooth care) traditions.
How to Use Ankol
| Form | Preparation | Dosage | Best Time |

| Root bark decoction | Boil 5–10 g dried root bark in 200 ml water; reduce to half | 50–100 ml twice daily | After meals |
| Bark powder | Dried stem bark ground to fine powder | 1–3 g with honey or warm water | Twice daily after meals |
| Leaf juice (topical) | Fresh leaves crushed; juice extracted | Apply directly to affected area | For skin conditions and wounds |
| Bark paste (topical) | Powdered bark mixed with water or sesame oil | Apply to joints or skin | For arthritis pain and skin diseases |
Side Effects and Precautions
Known Contraindications
- Pregnancy — alkaloid content may stimulate uterine contractions; avoid without medical supervision
- High Pitta conditions — heating quality may aggravate Pitta-driven inflammation in excess
- Debilitated individuals with very weak digestion — the strong bitter and pungent qualities may be too harsh
Drug Interactions
- CNS medications — alkaloids may interact with antiepileptic and sedative drugs
- Antiparasitic drugs — additive effects possible with pharmaceutical anthelmintics
Who Should Avoid
- Pregnant and breastfeeding women
- Children without qualified medical supervision
- Individuals with severe liver disease — alkaloid-rich preparations require adequate hepatic metabolism
Safe Dosage Range
Internal dose of Ankol bark powder: 1–3 g twice daily. Decoction: 50–100 ml twice daily after meals. Due to the potency of its alkaloids, Ankol should ideally be used under the guidance of a qualified Ayurvedic physician, particularly for internal use. Topical applications are generally safe.
Classical Text References
Charaka Samhita (Kalpa Sthana 12) lists Ankola among Vishagna (anti-poison) drugs and prescribes it for snake and insect bites. Sushruta Samhita (Kalpa Sthana 5) specifically names Ankola root paste as a remedy for visha (toxins) applied to wounds. Ashtanga Hridayam (Uttara Tantra 35) includes Ankola in formulations for skin diseases (Kushtha) and parasitic infections.
Frequently Asked Questions About Ankol
