Snuhi (Euphorbia neriifolia): Toxic Latex Warnings & Safety Facts

Warning: The milky latex of snuhi is toxic. Skin contact causes burns and blistering, eye contact can cause severe corneal injury and even blindness, and swallowing it can cause vomiting, intestinal damage, and collapse. Snuhi is not a home remedy, and there is no established safe dose for home medicinal use. If latex touches eyes or is swallowed, seek medical care immediately.

TL;DR

Snuhi (Euphorbia neriifolia) is an Indian spurge whose milky latex is toxic: skin contact causes burns and blistering, eye contact can cause severe corneal injury and blindness, and swallowing it can cause vomiting, intestinal damage, and collapse. It is not a home remedy, and there is no established safe dose for home medicinal use; seek medical care immediately after exposure.

What it is

Snuhi is Euphorbia neriifolia L., a succulent, cactus-like xerophytic shrub or small tree in the spurge family (Euphorbiaceae), commonly called the Indian spurge tree and widely planted as a thorny hedge across India (MDPI review). Like all spurges, it bleeds a milky white latex from any cut or broken part (same review). That latex contains irritant diterpene esters (of the phorbol, ingenol, and 12-deoxyphorbol types) and a cytotoxic protein called euphorbon, which are considered responsible for its toxicity (same review).

Traditional use

Historical and folk sources describe uses of the latex as a purgative and for piles, asthma, skin ailments, and tumors, and of the leaves and roots in folk medicine (phytopharmacological review; Euphorbia traditional-medicine review, PMC). These practices predate modern toxicology, and the same scientific literature documents severe injury from the plant. They are historical claims, not safe instructions: snuhi latex is not something to prepare or apply at home, and this article gives no method for doing so.

What modern research says

Skin and eye injury: documented in case series

The human evidence on snuhi-type latex is a record of harm. Ophthalmologists state plainly that "the milky sap or latex of Euphorbia plant is highly toxic and an irritant to the skin and eye" (Basak et al., Indian J Ophthalmol 2009). In their series of three patients with accidental eye exposure, all suffered severe burning and blurred vision, with findings ranging from keratoconjunctivitis and corneal swelling to anterior uveitis and raised eye pressure. All required medical treatment and took 10–14 days to resolve (same paper).

A separate series of four Euphorbia-sap eye injuries found a characteristic course: immediate burning and light sensitivity, then progressive corneal surface breakdown with delayed healing taking about 9 days, attributed to a diterpenoid compound in the sap with cell-damaging activity (Scott & Karp, Br J Ophthalmol 1996). A comprehensive review of E. neriifolia specifically warns that skin contact produces irritation, inflammation, and blistering, and that eye exposure ranges from mild conjunctivitis to severe kerato-uveitis that "may result in permanent blindness" (MDPI review). The plant's roots and leaves have even been used as fish poison (same review).

Ingestion: dangerous and potentially fatal

Swallowing the sap is described as potentially fatal: reported effects include convulsions, burning pain in the stomach, vomiting, diarrhea, and coma, with the sap able to perforate and inflame the intestinal walls (MDPI review). This is not a plant to ingest in any amount.

Efficacy research: limited and inconclusive human evidence

Laboratory and animal studies report anti-inflammatory, analgesic, wound-healing, antimicrobial, and antioxidant activity for E. neriifolia extracts and compounds (MDPI review). These are preclinical findings only: the one small 2022 human study of leaf juice in mild/moderate COVID-19 patients (60 patients) was too small to support conclusions (Pramanik et al., Euroasian J Hepato-Gastroenterol 2022), and there is no basis for medicinal use in people.

Dosage

There is no established safe dose for snuhi: not for the latex, the leaves, or any preparation of the plant. Do not ingest snuhi latex or apply it to skin, eyes, or wounds at home in any amount. The absence of a dosage section with numbers in this article is deliberate: this plant's toxic latex has no established therapeutic window for home use.

Safety & contraindications

Avoid handling snuhi without protection: wear eye protection if you must prune or move the plant, wash any contacted skin thoroughly with running water (Basak et al. 2009; MDPI review). If latex enters the eyes, irrigate immediately with clean water and seek emergency eye care: case series show the injury can worsen over the first day even after irrigation (Scott & Karp 1996). If swallowed, seek emergency medical care immediately: do not attempt to treat it yourself. Do not use snuhi latex at home for warts, piles, or any skin condition: see a clinician or dermatologist instead. There are no safety data for pregnancy or breastfeeding, and given the documented toxicity, exposure must be avoided in both.

FAQs

Is snuhi poisonous?

Yes. Its milky latex is toxic to skin and eyes and dangerous if swallowed: causing burns, blistering, severe eye inflammation, vomiting, and potentially fatal intestinal injury (MDPI review).

What happens if snuhi latex gets in your eyes?

Expect immediate severe burning, light sensitivity, and blurred vision, with corneal injury that can worsen over the first day. Documented cases range from keratoconjunctivitis to severe kerato-uveitis, and permanent blindness is possible (Basak et al. 2009; MDPI review). Irrigate immediately and get emergency eye care.

Is snuhi used in Ayurveda?

Historical and folk sources describe traditional uses of the latex and other parts, but modern case reports document severe toxicity from the same plant (phytopharmacological review; MDPI review). Traditional mention is not a safety endorsement, and it is not a home remedy.

Is there a safe dose of snuhi?

No. There is no established safe dose for any part or preparation of the plant for home medicinal use. The only human study identified, a small 2022 study of leaf juice in mild/moderate COVID-19 patients, was too small to support conclusions (Pramanik et al., Euroasian J Hepato-Gastroenterol 2022). Do not self-dose.

Can I use snuhi latex at home for warts or piles?

No. Applying the latex to skin or sensitive areas risks chemical burns and severe inflammation. See a clinician or dermatologist for safe, proven treatments.

How should the plant be handled?

Ideally not at all. If handling is unavoidable, wear eye protection and wash exposed skin thoroughly with running water (Basak et al. 2009; MDPI review).
