Hamsapadi: Traditional Uses, Evidence & Safety

Q: Is Hamsapadi the same as Adiantum philippense?

In some taxonomies, Adiantum lunulatum is treated as a synonym of Adiantum philippense L.: they refer to the same maidenhair fern drug (Suhail et al., 2022).

TL;DR

Hamsapadi is the whole plant of Adiantum lunulatum Burm., a maidenhair fern. Ethnobotanical records describe its use for loose motion and burning sensations, and tribal use of its rhizome as a contraceptive. Modern evidence is limited to laboratory and animal studies, including antifertility effects in rats; no human trials were identified in the cited sources. Avoid while pregnant or breastfeeding.

What it is

Hamsapadi is the Ayurvedic drug prepared from the whole plant of Adiantum lunulatum Burm., a delicate maidenhair fern in the Pteridaceae family. A pharmacognostic study of whole-plant material compared its features against the Ayurveda Pharmacopoeia of India's description and set quality parameters for the crude drug (Amrita study). In some taxonomies A. lunulatum is treated as a synonym of Adiantum philippense L. (Suhail et al., 2022, review).

Traditional use

Ethnobotanical records for A. lunulatum describe crushed leaves and juice used for loose motion, and fresh frond extract used for burning sensations (Suhail et al., 2022). The same review records tribal use of powdered rhizome as a contraceptive and antifertility effects in male rats. These are traditional and preclinical reports, not clinical findings: and the antifertility signal is itself a safety warning (see below).

What modern research says

Human evidence is absent in the cited sources. A 2022 review of A. lunulatum/*A. philippense* catalogs its ethnopharmacology and phytochemistry but reports only laboratory findings, antioxidant and antibacterial activity in vitro, and animal studies (antifertility, antidiabetic), with no controlled human studies (Suhail et al., 2022). No human trials of Hamsapadi were identified in the sources reviewed for this article. Pharmacognostic work establishes identity and quality standards for the drug; it does not test efficacy (Amrita study).

Note: a separate review exists for a different maidenhair fern species, Adiantum capillus-veneris: its findings, also largely preclinical, cannot be transferred to Hamsapadi (maidenhair review).

Dosage

No reliable clinical or pharmacopoeial therapeutic dose for Hamsapadi appears in the sources reviewed for this article: published modern evidence is limited to laboratory and animal studies, so no dosage can be supported here. Do not use this article to pick a dose; ask a qualified Ayurvedic practitioner.

Safety & contraindications

No published human safety data for Hamsapadi were found in the sources reviewed. Because ethnobotanical literature records tribal use of A. lunulatum rhizome as a contraceptive, and a 2022 review documents antifertility effects in male rats, it should be avoided in pregnancy and while trying to conceive (Suhail et al., 2022). Avoid it while breastfeeding and in children, and do not use it as unsupervised self-medication. Only authenticated whole-plant material should ever be considered, and only under qualified practitioner guidance.

FAQs

What is Hamsapadi?

Hamsapadi is the Ayurvedic name for the whole plant of the maidenhair fern Adiantum lunulatum Burm., whose identity has been confirmed in pharmacognostic work against the Ayurveda Pharmacopoeia of India's description (Amrita study).

Is Hamsapadi the same as Adiantum philippense?

In some taxonomies, Adiantum lunulatum is treated as a synonym of Adiantum philippense L.: they refer to the same maidenhair fern drug (Suhail et al., 2022).

Are there clinical trials on Hamsapadi?

No. The sources reviewed for this article report only laboratory and animal findings (antioxidant, antibacterial, antifertility) and pharmacognostic standardization work; no human trials of Hamsapadi were identified in those sources (Suhail et al., 2022; Amrita study).

Is Hamsapadi safe?

No human safety data were found in the sources reviewed. Given ethnobotanical records of tribal contraceptive use and an animal study reporting antifertility effects in rats, avoid it in pregnancy and while trying to conceive. Also avoid it while breastfeeding and in children, and do not self-medicate (Suhail et al., 2022).
