Mexican Mint

Indian borage

Mexican Mint (Plectranthus amboinicus), also known as Indian borage or Cuban oregano, is an aromatic herb with thick, fuzzy leaves. It is mildly toxic to cats because it contains strong essential oils. Cats do not have the right liver enzymes to break down these oils. When a cat eats the plant, compounds like carvacrol and thymol directly irritate their stomach and digestive tract. A cat that nibbles on Mexican mint may drool, vomit, have diarrhea, or lose its appetite. The strong smell usually keeps cats away, but if your cat eats a large amount or if the symptoms do not go away, contact a veterinarian.

Important Notes

Toxic compounds: carvacrol, thymol, and camphor-related volatile oils throughout the plant

Mechanism: these terpenoid oils irritate the gastrointestinal mucosa directly and may cause mild liver stress with repeated exposure

Symptoms: vomiting, diarrhea, drooling, lethargy; symptoms are generally mild and self-limiting

The strong aroma may deter most cats, but some find the scent attractive

Contact your vet if symptoms persist or if large amounts were consumed
