Kanchanar Guggulu

A classical Ayurvedic multi-herb tablet (Bauhinia variegata bark plus guggul resin) sold for thyroid nodules and lymph swelling. Despite centuries of traditional use, there is no completed placebo-controlled trial in PubMed testing it for any of those uses.

Evidence last reviewed: August 2026

What the science says

  • Thyroid support Limited evidence

    The only thyroid-related record indexed in PubMed is a 2024 protocol for a randomized trial comparing levothyroxine with Kshar Basti and Kanchanar Guggul in hypothyroidism. A protocol describes a planned study, not a result, so no efficacy conclusion can be drawn.

  • Lymphatic and glandular swelling Limited evidence

    Published work on the formula is laboratory-level: an in vitro study characterised cytotoxic and antiproliferative activity of kanchnar guggulu on cell lines. There is no human data on gland or lymph node size.

Dosage & safety

Studied doseTraditional practice uses roughly 1–2 tablets (about 500 mg each) two or three times daily after meals, often with warm water. No dose has been validated in a controlled human trial.
SafetyGuggul-containing formulas can cause nausea, loose stools, headache and skin rash, and guggul induces liver enzymes that can lower blood levels of drugs such as propranolol and diltiazem. Avoid in pregnancy, and do not use as a substitute for levothyroxine or for medical evaluation of a thyroid nodule.
