Isodon

Isodon is a genus of flowering plants in the family Lamiaceae, commonly known as the mint family. The genus is native to East Asia, with most species found in China and Southeast Asia. Isodon plants are herbaceous perennials or shrubs, typically with opposite, toothed leaves and whorls of flowers that can be white, pink, or purple. Many species are known for their medicinal properties, with various parts of the plant used in traditional Chinese medicine for treating ailments such as inflammation, pain, and infections.

The taxonomy of Isodon has been subject to some revision. Historically, many species were classified under the genus Plectranthus, but genetic studies have led to their reclassification. The name Isodon is derived from Greek words meaning "equal tooth," referring to the even margins of the leaves found in some species. While not widely cultivated as ornamentals, some Isodon species are of interest for their distinctive floral displays and potential as sources for new medicinal compounds. Research continues to explore the phytochemical profiles and pharmacological activities of various Isodon species.
