Elephant ear taro, or Colocasia esculenta, has various traditional medicinal uses, though these are not scientifically proven and the plant contains toxic calcium oxalate crystals when fresh. Historically, the leaves have been applied as a poultice to boils, used to reduce swelling from insect stings, and in decoctions to promote menstruation or treat stomach problems. The roots and corms are sometimes used to treat wounds, conjunctivitis, swollen lymph glands, and digestive issues, while the seeds are said to have antimicrobial properties.
External Applications (Poultices & Topical)
Boils and Sores: Heated leaves are applied as a poultice to boils and infected sores to aid healing.
Insect Stings: A cut stem leaf can be rubbed on insect stings to prevent swelling and pain.
Wounds: Plant parts are used in treatments for wounds.
Furunculosis (Boils): A plaster made from the plant’s rhizome is applied topically for boils.
Internal Applications (Decoctions & Oral)
Stomach Problems & Cysts: A decoction of leaves, sometimes with other plants, is used to relieve stomach pain and treat cysts.
Conjunctivitis: The sap from the leaf stalk is used to treat eye inflammation.
Menstruation: A leaf decoction is drunk to promote menstruation.
Appetite & Digestion: The scraped stem can be used with other plants to stimulate appetite. Cooked leaves may also support digestive health.
Other Uses
Anti-bacterial: The plant is noted for its antibacterial properties.
Hypotensive: It is also used to help lower blood pressure.

Important Precautions
Toxicity: All parts of the plant contain calcium oxalate crystals, which are toxic when fresh and can cause a burning sensation and swelling in the mouth, throat, and stomach.
Preparation: Cooking the plant thoroughly or fully drying it removes the calcium oxalate crystals, making it safe for consumption.
Caution for Certain Conditions: People with kidney stones, gout, arthritis, or rheumatism should exercise caution with taro.
