Understanding Mexican Mint: A Case of Mistaken Identity
Mexican mint, with the botanical name Plectranthus amboinicus, is a succulent perennial herb that is, in fact, edible. The confusion often stems from its many common names, which include Cuban oregano, Indian borage, Spanish thyme, and Mexican marigold, the latter of which is a completely different plant (Tagetes lucida). Unlike true mint (Mentha spp.) or oregano (Origanum vulgare), Plectranthus amboinicus is not a true member of either genus, but it belongs to the same family, Lamiaceae, and shares similar aromatic qualities. This herb is commonly grown for its culinary and medicinal properties.
What Does Mexican Mint Taste and Smell Like?
The taste and aroma of Mexican mint are a complex, pungent combination that is often described as a savory mix of oregano, thyme, and a hint of mint or anise. The flavor is much stronger and more intense than traditional oregano, so a little goes a long way. The leaves are fleshy, almost succulent, with a covering of soft, fuzzy hairs, which releases a strong fragrance when crushed. This potent profile makes it a favorite for adding a robust flavor to a variety of dishes without needing a large quantity.
Culinary Applications and Best Practices
Due to its strong flavor, Mexican mint should be used sparingly, especially when first experimenting with it in the kitchen. Here are some common culinary uses:
- Fresh: The fresh leaves can be added to salads, salsas, and dressings for a burst of unique flavor.
- Cooked: The herb stands up well to heat, making it suitable for soups, stews, and braised meat dishes. It's a great addition to bean dishes and curries.
- Marinades and Sauces: Its robust flavor makes it an excellent addition to marinades for chicken, beef, or game, providing a savory, earthy note.
- Teas and Infusions: A few leaves can be brewed into a soothing herbal tea, which is traditionally used to aid digestion and alleviate cold symptoms.
- Seasoning: The leaves can be dried and ground into a powder to be used as a seasoning blend, though drying is more challenging due to its high oil and water content.

Growing Mexican Mint for a Home Harvest
Mexican mint is a robust and easy-to-grow plant, making it a great addition to any home garden or kitchen. It thrives in warm climates (USDA hardiness zones 9-11) but can be grown as an indoor houseplant or moved indoors during colder months.
- Light: Provide bright, indirect light or partial shade. Too much direct sun can scorch the leaves.
- Soil: Plant in well-draining soil, either in a pot or directly in the garden. A sandy, well-aerated mix is ideal.
- Watering: As a succulent-like plant, it prefers for the soil to dry out between waterings to prevent root rot. Water deeply but infrequently.
- Propagation: It is very easy to propagate new plants from stem cuttings. Simply snip a 4- to 6-inch stem, remove the lower leaves, and place the cutting in water or moist soil until roots develop.
Health Benefits and Safety Precautions
In traditional medicine, Mexican mint is valued for a variety of health benefits, attributed to its anti-inflammatory, antimicrobial, and antioxidant properties. Historically, it has been used to treat respiratory ailments, digestive issues like bloating and indigestion, and skin conditions.
