Brihati (Solanum indicum): Traditional Uses, Evidence & Safety

TL;DR

Brihati (Solanum indicum) is a nightshade-family root used in Ayurveda for cough and breathing complaints, and is one of the Dashamula ten-root group. Human clinical evidence for it is essentially absent; most small studies concern the related species Kantakari. No verified dose exists. Because Solanum plants contain glycoalkaloids, it should only be used as authenticated root medicine under qualified guidance.

What it is

Brihati is Solanum indicum L., a prickly shrub in the nightshade family (Solanaceae). The Ayurvedic Pharmacopoeia of India (Vol. II) defines the official drug as the dried root of Solanum indicum, characterized by steroidal alkaloid and steroid constituents (API Vol. II monograph, third-party scan). It is one half of the classical pair "Brihati Dwaya": Brihati (S. indicum) together with Kantakari (Solanum xanthocarpum Schrad & Wendl, also cited as S. surattense): and both are members of Dashamula, the canonical group of ten roots (Rabb 2022, Brihati Dwaya review).

A note on names: S. indicum and S. xanthocarpum are related but distinct species, reviews of the classical Brihati Dwaya pair keep them taxonomically separate, and they should not be treated as interchangeable. Study results on one do not apply to the other (Rabb 2022).

Traditional use

The API monograph records Brihati root's traditional indications as Svasa (dyspnoea/breathing difficulty), Kasa (cough), Hrdroga, Jvara (fever), and Agnimandya (weak digestion), with the classical preparation a decoction (API Vol. II monograph, third-party scan). Reviews of the Brihati Dwaya pair describe its long-standing respiratory use in Ayurvedic formulations, most often as part of Dashamula-based preparations (Rabb 2022). These are traditional indications, not clinical proof: and as the next section explains, the human evidence base is thin.

What modern research says

Honestly: **robust controlled human trials of Solanum indicum Brihati were not located.** The published clinical work on respiratory effects in this plant group, for example, a small pilot study in bronchial asthma, was conducted on the related species S. xanthocarpum (Kantakari), not on API-defined Brihati (pilot study, Academia.edu). Because the two are distinct species with different chemistry, those results cannot be claimed for Brihati.

The API monograph characterizes Brihati root by its steroidal alkaloid and steroid constituents, but this is chemistry, not evidence of efficacy (API Vol. II monograph, third-party scan). Brihati's traditional respiratory uses remain traditional claims awaiting proper clinical testing.

Dosage

No verified dose can be stated from the accessible sources. The API Vol. II monograph defines the drug as the dried root of S. indicum prepared as a decoction, but the precise pharmacopoeial quantity could not be confirmed from the accessible copy, and secondary sources give conflicting figures: so no dose is stated here (API Vol. II monograph, third-party scan). Given the sparse safety data, Brihati should only be used as authenticated root material under the guidance of a qualified Ayurvedic practitioner: not self-dosed.

Safety & contraindications

Brihati belongs to the nightshade family and contains steroidal alkaloids/glycoalkaloids (API Vol. II monograph, third-party scan). Because human safety data are sparse, only authenticated root material should be used, under qualified practitioner guidance.

Practical cautions:

Note the balance: the glycoalkaloid caution concerns the plant family and its chemistry at sufficient exposure; it is not a claim that a standard decoction of authenticated Brihati root causes poisoning. No human toxicity data for Brihati preparations specifically were identified in the reviewed sources, which is itself a reason for practitioner-guided use.

FAQs

What is Brihati?

Brihati is the Ayurvedic drug prepared from the dried root of Solanum indicum L., a nightshade-family shrub, as defined by the Ayurvedic Pharmacopoeia of India (API Vol. II monograph, third-party scan).

Is Brihati the same as Kantakari?

No. Brihati is Solanum indicum; Kantakari is the related species Solanum xanthocarpum. They form the classical pair "Brihati Dwaya" and both belong to Dashamula, but they are distinct species: study results on one do not apply to the other (Rabb 2022).

What is Brihati used for in Ayurveda?

The API lists traditional indications including Svasa (breathing difficulty), Kasa (cough), fever, and weak digestion, prepared as a decoction (API Vol. II monograph, third-party scan). These are traditional uses, not clinically proven effects.

Are there human studies on Brihati?

No robust controlled human trials of Solanum indicum Brihati were located. Small pilot studies in this plant group concern the related species Kantakari (S. xanthocarpum) and cannot be transferred to Brihati (pilot study).

Is Brihati safe?

Its safety in humans is poorly studied. As a nightshade-family plant containing steroidal alkaloids/glycoalkaloids, it should only be used as authenticated root material under qualified practitioner guidance. Safety in pregnancy, breastfeeding, and children has not been studied.
