Brihati: Benefits, Uses & Dosage

If you have ever wondered why so many classical cough and breathing formulas share the same short list of roots, Brihati is part of the answer. This prickly little plant turns up again and again in the old texts, usually side by side with its close cousin, quietly doing the work of clearing heavy, congested phlegm.

Brihati is known in English as Indian Nightshade or Poison Berry, and in Hindi as Badi Kateri. Its botanical name is Solanum indicum Linn., which places it in the nightshade genus. It grows as a prickly undershrub found commonly across India, and it bears small round berries that turn yellow when ripe.

The root, fruit, and whole plant are all used medicinally. Brihati is pungent and bitter, with a strong action against Kapha, the dosha of heaviness and mucus. That is why the Bhavaprakash Nighantu ties it to cough, asthma, and hiccup.

Brihati is one of the five roots of the small five-root group (Laghu Panchamula), and through that group it is a member of the classical ten-root formula Dashamoola. Paired with Kantakari, it forms the duo known as "the two Brihatis" (Brihati-dvaya), a pairing you will find throughout Ayurvedic pharmacy.

Brihati's uses all flow from one profile: pungent and bitter taste (Katu and Tikta Rasa), light, dry, and sharp qualities (Laghu, Ruksha, Tikshna Guna), a heating potency (Ushna Virya), and a pungent effect after digestion (Katu Vipaka). The Bhavaprakash Nighantu, Varga 3, classes it as pacifying Kapha and Vata.

Cough, Asthma, and Breathing

This is Brihati's home ground. The Bhavaprakash Nighantu names it as relieving cough (Kasahara) and relieving breathlessness or asthma (Shwasahara), and lists cough (Kasa) and asthma (Shwasa) first among its classical uses.

The reasoning is simple: pungent, bitter, dry, and hot qualities are the direct opposites of thick, cold, sticky Kapha in the chest. The Sharangadhara Samhita, Madhyama Khanda, Chapter 2, describes a decoction of the two Brihatis with Kantakari, Shati, Pushkaramula, Vacha, and Vibhitaka that alleviates Vata-Kapha disorders.

Hiccups

Hiccup (Hikka) appears directly in Brihati's classical list of uses. Charaka Samhita, Chikitsa Sthana, Chapter 23, records medicated smoke of brihati, kantakari, and adhaki leaves as a remedy for hiccups caused by poisoning. Read more on our hiccups page.

Digestion and Worms

Brihati is named as kindling the digestive fire (Deepani). The Astanga Hridaya, Sutrasthana, adds that the two Brihatis promote hunger and break up hard stools, while also increasing Pitta.

It is also classed as anthelmintic (Krimighna), meaning it acts against worms, and worms (Krimi) are among its listed uses. See parasites and worms.

Fever

The Bhavaprakash Nighantu includes fever (Jwara) among Brihati's five classical therapeutic uses, alongside cough, asthma, worms, and hiccup.

Hair Loss

The Sharangadhara Samhita, Uttara Khanda, Chapter 11, gives a short topical recipe for patchy hair loss (Indralupta): Brihati juice with honey. Its sharp, hot quality is the classical rationale for using it on a dormant patch. Details are on our hair loss page.

Kapha-Type Eye Congestion

The Sushruta Samhita, Uttara Tantra, Chapter 11, on Kapha-type conjunctivitis, describes placing a medicinal paste inside the ripening Brihati fruit. This is a practitioner preparation, never a home eye remedy.

Brihati is a therapeutic root, not a kitchen herb. Classical practice uses the root, fruit, and whole plant, most often as a powder (churna), a decoction (kashaya), or as part of a compound formula such as Dashamoola.

Choosing a Vehicle

The vehicle you take an herb with is called anupana. For Brihati, warm water is the standard choice. Honey is preferred when Kapha congestion dominates, since honey itself works against Kapha.

Pairing

Brihati almost always travels with Kantakari. If solo Brihati powder is hard to find, Dashamoola decoction gives you Brihati as one of its ten roots, balanced by the others.

Because of its heat and alkaloid content, keep to these ranges and use it for defined courses rather than indefinitely, ideally under a qualified practitioner.

Brihati is a useful classical herb, but it is not a gentle one. It belongs to the nightshade genus and contains steroidal alkaloids, chiefly solanine and solasodine. That is the main reason it is treated as a practitioner herb rather than something to experiment with at home.

Who Should Avoid It

• Pregnancy: avoid Brihati unless a qualified practitioner directs otherwise, because of its alkaloid content.
• Excess Pitta: the Astanga Hridaya notes that the two Brihatis increase Pitta, the dosha of heat. Skip it with burning, acidity, red and inflamed skin or scalp, or hot, burning eye flares.
• Active gastritis or hyperacidity: its heating, sharp nature can aggravate these.
• Autoimmune conditions or immunosuppressant medication: consult a practitioner first, as Solanum alkaloids may interact.

Practical Cautions

• Never put Brihati juice, paste, or extract into the eye.
• Do not forage the plant or eat the raw berries.
• Patch test any topical paste on the inner forearm for 24 hours first, and stop or dilute if it irritates.
• Stay within classical dose ranges and avoid long, unsupervised use.

Hiccups lasting longer than 48 hours, or eye symptoms with vision changes or no improvement in a few days, need medical evaluation.

Brihati is rarely the only option for a given problem. Here is how it compares with the herbs it is most often weighed against, based on their classical roles.

Comparison	Brihati	Alternative	Verdict
Brihati vs Kantakari	Pungent, bitter, heating; Kapha and Vata pacifying; member of Laghu Panchamula	Its classical partner; also in Laghu Panchamula, and together they form Brihati-dvaya	Not rivals. Classical formulas usually use both together for cough, breathlessness, and hiccup.
Brihati vs Ajwain for hiccups	Deeper respiratory remedy for hiccup with cough or chest congestion	Kitchen spice for ordinary hiccups after meals	Try Ajwain first for an everyday bout; Brihati fits hiccups with a respiratory layer.
Brihati vs Bhringaraj for hair loss	Topical juice with honey for patchy hair loss (Indralupta)	Lead hair tonic for diffuse, Pitta-type hair loss	Different patterns. Brihati on the patch, Bhringaraj for the wider scalp and internally.
Brihati vs Triphala for eye congestion	Internal only, for Kapha-type patterns; never in the eye	The classical eyewash and local treatment	Triphala for the eye surface; Brihati works upstream, internally.

A common thread: Brihati is heating and increases Pitta, so in any hot, burning, or acidic picture the cooler alternative is usually the better choice.

Our sources say little about Brihati for specific groups, so the guidance below is deliberately cautious. When in doubt, talk to a qualified Ayurvedic practitioner before using it.

Pregnancy & Nursing

Avoid Brihati during pregnancy. It contains steroidal alkaloids (solanine and solasodine), and our sources advise against it in pregnancy and recommend qualified supervision during breastfeeding.

Children

Our sources give no child-specific dosing or safety data for Brihati. Given its alkaloid content and heating nature, do not give it to children except under a practitioner's direct guidance.

Elderly

There is no elderly-specific guidance in our sources. Older adults with acidity, gastritis, or a hot, Pitta-type constitution should be especially careful, since the Astanga Hridaya notes Brihati increases Pitta. Anyone on immunosuppressants should consult a practitioner first.

Athletes

Our sources do not describe any athletic or performance use for Brihati. Its classical role is in cough, breathing, digestion, and Kapha congestion, not strength or endurance.
