Updated 2026-03-06| 4 min read| 2,191 found this helpful

Acalypha chamaedrifolia (Lam.) Mull. Arg.; Acalypha reptans Sw.

The highest concentration of toxic compounds is found in the plant's clear, irritant milky sap, though all parts carry some toxicity risk.

Exposure via ingestion or contact with skin/mucous membranes typically causes local irritation and gastrointestinal inflammation.

Treatment for exposure focuses on prompt decontamination and symptomatic management of irritation and inflammation.

Exposure RouteIngestion of any plant material; skin, eye or mucous membrane contact with milky sap

Toxic CompoundsDiterpene esters

First Aid & Prevention

First 30 Minutes

• For skin/eye exposure: Flush affected area with cool running water for 10-15 minutes to remove all sap residue
• For ingestion: Rinse mouth thoroughly with water; do not induce vomiting unless instructed by a medical/veterinary professional
• Remove all remaining plant material from the exposure site and surrounding area to prevent further contact

Contact Vet Immediately

• Your pet has ingested any quantity of the plant, or has had direct contact with its sap
• Your pet develops vomiting, diarrhea, drooling, pawing at the mouth/eyes, or skin redness after exposure
• Your horse is observed ingesting the plant, even if no immediate symptoms are present

Prevention

• Keep the plant out of reach of children, pets and livestock; avoid planting it in pastures or pet-accessible yards
• Wear gloves and eye protection when pruning or handling the plant to avoid contact with irritant sap
• Educate household members and caregivers about the plant's toxicity to prevent accidental exposure

Treatment & Prognosis

• Decontamination: Remove remaining plant material, administer activated charcoal for recent ingestion under professional supervision
• Symptomatic care: Provide anti-emetics, fluid therapy and anti-inflammatory medication to manage gastrointestinal irritation
• Monitor exposed individuals for 24-48 hours post-exposure to catch any delayed or secondary complications

Target Organs

Gastrointestinal tractSkinEyesOral mucous membranes

Mechanism of Action

• Diterpene esters act as potent irritants that trigger inflammation of mucous membranes and gastrointestinal tissue on contact or ingestion

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Small mammals (rabbits, guinea pigs, hamsters): High risk; even small ingestion amounts can cause severe gastrointestinal inflammation and systemic distress due to low body mass

Birds: Moderate risk; ingestion may cause oral irritation and digestive upset, with severe reactions possible in small passerine species

Ruminant livestock (cattle, sheep, goats): Moderate risk; ingestion of large quantities causes gastrointestinal distress and reduced feed intake, fatalities are rare

Confusion Risk

The following plants look similar and may be confused:

Other Acalypha species Acalypha spp.

Most Acalypha species have similar foliage and fuzzy red inflorescences; nearly all genus members produce irritant milky sap with comparable toxicity profiles
