Chaste Tree: Benefits, Uses & Dosage

If you live with stiff joints, a nagging headache, or swelling that flares after a long day, Chaste Tree deserves a place on your radar. The classical texts treat it as one of the most important anti-inflammatory plants in the whole tradition, and it is used far more on the skin than in the stomach.

In Sanskrit it is called Nirgundi, with the classical synonym (Sindhuvara), and in Hindi it is known as Sambhalu. Its English names are Chaste Tree and Five-leaved Chaste Tree, and our records list it botanically as Vitex agnus-castus Linn. It is a shrub with palmately compound leaves, meaning the leaflets fan out from one point like fingers on a hand, and it grows throughout India.

The Bhavaprakash Nighantu discusses Nirgundi alongside Priyangu, noting that some varieties of Priyangu were confused with it. The leaves, roots, and seeds are all used. Its best-known preparation is the simplest one: fresh leaves, warmed and wrapped over a swollen, painful joint as a poultice.

Its character is warming and drying. It tastes pungent and bitter (Katu and Tikta Rasa), and it has hot potency (Ushna Virya), which is why it suits cold, stiff, Vata and Kapha types of pain better than hot, inflamed Pitta conditions.

The Bhavaprakash Nighantu, Varga 2 lists five therapeutic actions (karma) for Nirgundi: anti-inflammatory, pain-relieving, hair-promoting, anti-parasitic, and fever-reducing. Each one follows from the same warm, pungent, bitter, dry profile.

Inflammation and Swelling

Nirgundi is classed as Shothahara (Shothahara), an herb that reduces swelling and inflammation. Its dry, light qualities (Ruksha and Laghu Guna) help draw out excess fluid from the tissue.

What sets it apart is that it is warm. Many anti-inflammatory herbs, such as Guduchi, are cooling. Nirgundi is one of the few that reduces swelling while also warming, which matters when the swelling sits in a cold, stiff joint.

Joint and Nerve Pain

It is also Vedanasthapana (Vedanasthapana), meaning it settles pain. The classical description names joint pain, headache, and inflammatory swellings among its uses, and the leaves are applied as a poultice for swelling and pain, much as they are for arthritis.

The Bhavaprakash Nighantu, Guduchyadi Varga places it as a classical herb for sciatica (Gridhrasi), a Vata disorder of the sciatic nerve. It is used the same way for nerve inflammation, where warmth plus anti-inflammatory action is what the picture calls for.

Hair and Scalp

Nirgundi is named Keshya (Keshya), hair-promoting. It is not the first herb most practitioners pick for hair loss; that role goes to Bhringaraj. Its niche is the inflamed, congested, oily scalp, where its anti-inflammatory and drying action clears the ground for the follicle.

Worms and Parasites

The text calls it Krimighna (Krimighna), an herb that destroys worms. Worm infestation is listed among its classical uses, which links it to parasites. Internal use for this purpose belongs under a practitioner's guidance.

Fever

It is also listed as Jvarahara (Jvarahara), an herb that relieves fever. Our sources record the action but give little detail on how it is used for fever, so treat this as a classical note rather than a home remedy.

Nirgundi is used mostly on the outside of the body. The medicated oil Nirgundi Taila, sesame oil infused with the leaves and root, and the warm leaf poultice do most of the work. Internal forms are kept for stubborn or chronic cases.

Applying the oil

Warm the oil in a small steel bowl set over hot water rather than in a microwave, and test it on your inner wrist. Massage it into the painful area for 10-15 minutes, then apply a hot water bottle or steamed cloth. This pairing of oiling and warmth follows the classical approach to oil massage and sweating therapy.

Making a poultice

Warm a handful of leaves on a dry skillet until they wilt and smell fragrant. Wrap them in a soft cloth and lay them over the swollen area.

Vehicle for internal use

The vehicle (Anupana) you take a herb with shapes its effect. Take the decoction with warm water and a pinch of dry ginger when pain comes with heaviness and morning stiffness. For thin, dry, shooting Vata pain, add a teaspoon of ghee or warm sesame oil to soften Nirgundi's drying quality.

Used on the skin, Nirgundi is one of the gentler herbs in the Ayurvedic kit. Most of the cautions apply to taking it internally.

External use

Nirgundi Taila and leaf poultices are considered very safe. If your skin is sensitive, patch test the oil on a small area for 24 hours before a full application. Always test warmed oil or leaves on your wrist so you do not burn the skin.

Internal use

• Pregnancy: avoid internal Nirgundi.
• Heavy menstrual bleeding: avoid internal use while bleeding is heavy.
• Hormonal medication: chaste-tree compounds can shift hormonal patterns. If you take oral contraceptives, hormone replacement, fertility drugs, or finasteride, talk to a practitioner before taking it internally.
• Other prescriptions: separate internal doses from prescription drugs by at least two hours.

Constitution

Nirgundi is hot and drying. That is its strength for cold, stiff, swollen conditions, but it also means people who already run hot (a Pitta pattern) or who are very dry may find internal use aggravating. Adding ghee or sesame oil to the dose softens its drying effect.

When to see a doctor

If back or leg pain comes with progressive weakness, numbness between the legs, or loss of bowel or bladder control, seek emergency care. No herb replaces that.

Nirgundi is usually compared with other herbs for pain, inflammation, and hair. The key question each time is whether you need warmth or cooling, and outside or inside work.

Comparison	Chaste Tree	Alternative	Verdict
Chaste Tree vs Guduchi	Warm anti-inflammatory, mostly external	Cooling anti-inflammatory, taken internally	Choose Nirgundi for cold, stiff, Vata or Kapha swelling. Choose a cooling herb when the inflammation feels hot.
Chaste Tree vs Yogaraja Guggulu	Local pain and swelling, via oil and poultice	Internal formula that clears Ama (undigested metabolic residue) in chronic joint and nerve pain	They work as a pair: Nirgundi on the outside, Yogaraja Guggulu on the inside.
Chaste Tree vs Ashwagandha	Relieves pain and swelling at the site	Rebuilds depleted nerve tissue	Use Nirgundi for the pain layer and Ashwagandha when the pattern is thin and depleted. Many sciatica protocols use both.
Chaste Tree vs Bhringaraj	Warm, second-line hair herb for an inflamed, oily, congested scalp	Cooling, first-line hair herb	Start with Bhringaraj for most hair loss. Pick Nirgundi when the scalp is heavy, oily, or inflamed.

Our sources give clear guidance for some groups and very little for others. Where the data is thin, the safest path is external use only.

Pregnancy & Nursing

Avoid internal Nirgundi during pregnancy. Chaste-tree compounds can shift hormonal patterns, so the same caution is sensible while nursing. Ask a practitioner before using even the oil on large areas of the body during this time.

Women with heavy periods or on hormones

Avoid internal use during heavy menstrual bleeding. If you take oral contraceptives, hormone replacement, or fertility medication, speak with a practitioner before taking Nirgundi internally. The oil applied externally is not considered a concern.

Children

Our sources do not give pediatric doses. Keep internal use for children in the hands of a qualified practitioner, and patch test any oil on a small area first.

Elderly

Stiff joints and chronic Vata pain are common with age, and warm Nirgundi oil massage suits that picture well. Because the herb is drying, older adults with very dry skin or digestion may prefer oil-based forms, or internal doses taken with ghee.

Athletes

For sore, swollen joints after training, a warm leaf poultice or Nirgundi Taila massage followed by heat targets local pain and swelling. Internal use is not needed for this.
