What is Śārapuṅkhā?

Śārapuṅkhā is a single-herb Ayurvedic medicine made from the whole plant of Tephrosia purpurea, also known as wild indigo or purple tephrosia. It is a single drug in Ayurveda, meaning it is given on its own rather than as part of a fixed multi-herb formula. Traditional practitioners use it mainly for the liver and spleen, and for wounds that heal slowly.

The honest verdict comes first: this is a well-documented staple of one tradition with very little human trial evidence behind it. Almost everything known about its chemistry comes from laboratory and animal work. Long traditional use tells you a plant has been trusted for centuries; it is not proof that it works, and that caveat is stated here once for the whole page.

One thing sets this plant apart from a gentle kitchen herb. It contains rotenoids, a group of natural compounds chemically related to rotenone, an insecticide that is toxic in quantity. For that reason this page treats Śārapuṅkhā with real caution rather than as a routine everyday supplement.

If you are thinking of using it for a liver or spleen problem, get a diagnosis first. Liver disease needs testing and monitoring that no herb can replace.

How does Śārapuṅkhā work?

No one has shown in people how Śārapuṅkhā works. What follows is what laboratory and animal studies suggest, not established fact.

Extracts of the plant have reduced markers of liver stress in rats given liver-damaging chemicals. Researchers think antioxidant compounds in the plant may limit damage from unstable molecules called free radicals. Whether this happens at doses a person could safely take is unknown.

Other animal work reports lower blood sugar, lower blood fats and reduced swelling after dosing with plant extracts. These are early signals in animals, not proven effects in humans.

In Ayurvedic terms the herb is described as bitter and pungent in taste, heating in action, and as acting on the liver, spleen and digestive fire. That is a traditional framework for choosing the herb, not a biological explanation.

What forms does Śārapuṅkhā come in?

Śārapuṅkhā is sold and used in a few simple forms. Whole-plant powder (churna) is the most common.

Other forms include:

Dried whole plant or root for making a water decoction (kwatha), a strong tea simmered down from the herb.

Capsules or tablets of the dried powder.

Liquid extracts and syrups, sometimes combined with other liver herbs.

Fresh juice (svarasa) of the leaves, used traditionally in India.

Pastes and oils applied to the skin over wounds or swellings.

There is no agreed standard for how much active compound a product should contain. Buy only from a supplier who tests for identity and heavy metals, and avoid unlabelled loose powders.

Where it comes from:

Śārapuṅkhā appears in classical Ayurvedic plant texts, including the Bhāvaprakāśa Nighaṇṭu, where it is grouped with herbs for the liver and spleen. Its name refers to the arrow-like shape of its leaf arrangement.

It has been a recognised staple of Ayurvedic practice in India for many centuries, and folk healers across South Asia have used it for fevers, wounds and swollen abdomens. It is also a common roadside weed and a soil-improving cover crop.

Its standing is strong within Ayurveda but it is not a shared classical herb of several unrelated traditions.

What does Śārapuṅkhā help with?

• Liver complaints described in Ayurveda as yakrit disorders: This is the herb's main traditional use, and the reason most people look it up. Rat studies show extracts reduce raised liver enzymes after chemical injury, but that has not been repeated in people in any trial we could identify. Do not use it in place of testing and treatment for hepatitis, fatty liver or any diagnosed liver disease.
• Enlarged spleen (plihodara) in traditional use: Classical Ayurvedic texts name Śārapuṅkhā for plihodara, a traditional category covering a swollen abdomen and enlarged spleen. There is no modern human evidence for this use. An enlarged spleen has serious possible causes, including infection and blood disease, and needs a doctor.
• Slow-healing wounds and skin sores (applied to the skin): Folk practice applies a paste of the leaves to wounds and boils. Some animal wound studies report faster closure with plant extracts. Human evidence is absent, and an infected or non-healing wound should be seen by a clinician rather than self-treated.
• Poor appetite and sluggish digestion: The bitter taste is the traditional reason for this use; bitter herbs are given before meals in Ayurveda to stimulate appetite. This is traditional reasoning, not a tested effect. No human trials support it.
• Coughs and mild breathing complaints in folk use: Village medicine in parts of India uses decoctions for coughs and wheezing. The evidence here is purely traditional report. If breathing is difficult, this is not an appropriate remedy.

Which foods are rich in Śārapuṅkhā?

This is a medicinal plant, not a food. It is not an ingredient in any normal diet and should not be eaten as a vegetable or tea for pleasure.

What are the side effects of Śārapuṅkhā?

• Nausea and stomach discomfort
• Vomiting, especially at higher doses
• Loose stools or diarrhoea
• Bitter taste and mouth dryness
• Skin rash or itching in people sensitive to the plant
• Possible drop in blood sugar (hypoglycaemia), seen in animal studies
• Headache or dizziness reported occasionally

Good to know:

Stomach upset is the most common problem and usually settles when you stop. Most reports of side effects come from traditional practice rather than from formal safety studies.

The serious concern is chemical, not anecdotal. The plant contains rotenoids, relatives of the insecticide rotenone, which is toxic to nerve and muscle cells at high exposure. Because of this, large doses, concentrated extracts and long unbroken use are not safe choices.

Stop taking it and get medical advice if you notice yellowing of the skin or eyes, dark urine, severe stomach pain or unusual weakness.

How much Śārapuṅkhā should you take?

• Recommended daily: There is no dose established by modern research, because the human studies needed to set one have not been done. Everything below is traditional practice, offered as information rather than as a recommendation. Ayurvedic texts and practitioners commonly use 1 to 3 grams of whole-plant powder a day, usually split into two doses. Decoctions are typically made from 3 to 6 grams of dried plant simmered in water. Because the plant contains rotenoids, more is not safer. Never exceed the amount on the product label, and take it only under an Ayurvedic practitioner who knows your medical history and your other medicines.
• Best time of day: Traditionally taken twice a day, in the morning and early evening. Bitter herbs given for appetite are usually taken shortly before a meal.
• With or without food: Usually taken with warm water, just before or just after food. Taking it with food may reduce stomach upset, which is the most common complaint.
• Time to effect: Not known, because it has not been measured in people. Traditional use assumes a gradual effect over one to three weeks rather than anything immediate.
• How long to take it: Traditional use is short-term, often two to four weeks for a specific complaint. There is no safety data for long-term daily use, so open-ended use is not sensible. Reassess after two weeks. If nothing has changed, stop and see a doctor rather than increasing the dose.
