What is 'Mother of All Herbs'? Identification and Edibility
The term "mother of all herbs" is a common name for the plant Plectranthus amboinicus, a member of the mint family (Lamiaceae). It is also widely known by other names, including Cuban oregano, Mexican mint, Indian borage, Spanish thyme, and broadleaf thyme. Originating in parts of southern and eastern Africa, it has since spread globally due to its hardiness and aromatic qualities. The herb features thick, fleshy, and succulent leaves with a strong, pungent aroma that combines notes of oregano, thyme, and mint.
Is Plectranthus amboinicus safe to eat?
Yes, Plectranthus amboinicus is safe for consumption in typical culinary amounts and is a staple in many cuisines around the world. Its leaves are used both fresh and cooked to flavor a variety of dishes. While it has been traditionally used in folk medicine for centuries, modern toxicological studies support its safety for general use. It's crucial to distinguish this plant from other herbs, such as motherwort (Leonurus cardiaca), which is not the same plant and has different properties and cautions.

- Additions to fresh dishes: Finely chopped leaves can be added sparingly to fresh salads or salsas for a burst of pungent flavor.
- Herbal teas: A simple and calming tea can be made by steeping a few fresh leaves in hot water.
- Baking and fillings: It can be used in baked goods, pizza toppings, or as a flavoring for bread and butter.

Comparison: Cuban Oregano vs. True Oregano
To better understand how to use Cuban oregano, it's helpful to compare it with the more common Origanum vulgare.
| Feature | Cuban Oregano (Plectranthus amboinicus) | True Oregano (Origanum vulgare) |
|---|---|---|
| Appearance | Large, fuzzy, succulent leaves with toothed edges. | Small, smoother, non-succulent leaves. |
| Flavor Profile | Very pungent, earthy, with strong oregano, mint, and camphor notes. A little goes a long way. | Generally sharper, with varying intensity based on subspecies (e.g., Greek oregano). |
| Best Use | Cooked dishes, stews, marinades. Holds up well to heat. | Both cooked and fresh dishes, but flavor can diminish with prolonged cooking. |
| Growth Habit | A fast-growing, semi-succulent that prefers warmer climates but can be grown indoors. | A more traditional, non-succulent herb that is cold-hardy in many zones. |
Cautions and Best Practices
While generally safe, a few important considerations should be noted before consuming this herb, especially in larger quantities.
- Dosage: The flavor is potent, so use sparingly in culinary applications to avoid overpowering other ingredients.
- High-Dose Extracts: As with many medicinal herbs, high-dose extracts or supplements should be approached with caution. Animal studies on high-dose aqueous extracts have shown some dose-dependent toxicity, though it is not a concern for normal culinary use.
- Pregnancy and Nursing: Due to its traditional uses and lack of extensive research, pregnant and nursing individuals should consult a healthcare professional before using it medicinally.
- Misidentification: Always confirm the plant's identity. There are other plants with similar common names. For example, motherwort (Leonurus cardiaca) is a different herb with different risks.
