Snuhi: Benefits, Uses & Dosage

Some Ayurvedic plants are gentle kitchen herbs. Snuhi is not one of them. This spiny, cactus-like shrub carries a milky latex that classical texts treat as a strong purgative, which is exactly why it belongs in the hands of trained practitioners rather than in a home remedy cupboard.

The plant described here is Triangular Spurge, botanically Euphorbia antiquorum Linn., known in Hindi as Thuhar or Tidhara and in Sanskrit as Tridhara Snuhi (Tridhara, "three-edged"), also called Vajrakantaka (Vajrakantaka, "thunderbolt thorn"). Its name comes from its stems, which have three distinct ridges. It grows in the dry regions of India.

The Bhavaprakasha Nighantu (Varga 3) groups it with the better-known Snuhi, Euphorbia neriifolia, and describes it as having similar but somewhat milder properties. Like that plant, its latex is used medicinally as a purgative and for skin conditions.

The classical record for Triangular Spurge is short and specific. The Bhavaprakasha Nighantu (Varga 3) lists three therapeutic actions (Karma, the classical term for what a herb does in the body) and four disease groups it is used for. Everything below comes from that entry.

Purgation

Its primary action is purgative (Virechana, meaning it drives strong bowel evacuation). This follows from its profile: a pungent taste (Katu Rasa), a sharp, penetrating quality (Tikshna Guna) and a hot potency (Ushna Virya). In classical practice purgation is a deliberate cleansing therapy, not a casual laxative.

Abdominal Disorders

The text lists it for abdominal disorders (Udara, a classical category of abdominal enlargement and distension), which sits naturally alongside its purgative action.

Skin Health

It is described as anti-dermatosis (Kushtaghna, "destroyer of skin disease") and is listed for skin disorders (Kushtha). The latex is used medicinally for skin conditions.

Worms

Its anthelmintic action (Krimighna, "destroyer of worms") places it among the classical remedies for parasites and worms (Krimi).

Swelling

The same entry lists it for swelling (Shotha), which is why it is connected with edema and swelling and with inflammation more broadly.

Triangular Spurge is not a herb you dose yourself. The medicinal part is the milky latex, and its main classical action is strong purgation (Virechana). Our sources give no standard home dose, no anupana (Anupana, the vehicle a herb is taken with) and no seasonal guidance for it, so we do not offer any.

The Bhavaprakasha Nighantu describes it as somewhat milder than Euphorbia neriifolia. Milder does not mean mild. Its sharp, hot and pungent nature is what makes it work, and also what makes it unsuitable for self-experimentation.

If you are drawn to it for skin, worms or swelling, take that interest to a practitioner, who can decide whether a purification-based approach suits you at all.

Most Ayurvedic herbs are gentle enough for everyday use. Triangular Spurge is a clear exception, and it is worth being direct about why.

Why It Needs Caution

• It is a strong purgative. The latex is used classically to force bowel evacuation (Virechana). That is a powerful effect on the body, not a mild digestive aid.
• Its nature is sharp and hot. It is pungent in taste and after digestion (Katu Rasa and Katu Vipaka), sharp (Tikshna) and heating (Ushna Virya). These are intense qualities.
• No home dose is established in our sources. Without a defined dose, there is no safe way to self-prescribe it.

What We Recommend

Do not take Snuhi latex internally or apply it on your own. Use it only if a qualified Ayurvedic practitioner prescribes and supervises it. Our sources do not record specific drug interactions, pregnancy data or overdose signs; that absence is a reason for more caution, not less.

Triangular Spurge is rarely compared with everyday supplements, because it is not one. The comparisons that matter are with its close relative and with its own classical role.

If you came here looking for a gentle daily herb for digestion or skin, Snuhi is not that herb. Ask a practitioner which gentler option fits your situation.

Because Triangular Spurge is a strong, sharp, heating purgative, caution applies to everyone. For the groups below, our sources contain no specific guidance, so the safe answer is conservative.

Pregnancy & Nursing

Avoid. A strong purgative (Virechana) with hot, sharp qualities is not something to take while pregnant or nursing, and our sources give no data supporting its safety in either situation.

Children

Avoid. No pediatric use or dose is recorded in our sources.

Elderly

Not for self-use. Strong purgation is demanding on the body, so any use in older adults should be decided by a qualified practitioner.

Athletes

There is no performance use for this plant in our sources. Its classical role is purgation and treatment of skin disease, worms, abdominal disorders and swelling, all under supervision.
