St John's wort (Hypericum perforatum) is a perennial plant with bright yellow flowers, one of the best-known medicinal plants. The flowering aerial parts are used for teas and oils, traditionally valued for supporting well-being. The plant is hardy, prefers sun and poor soils, and often grows wild in meadows. The red oil obtained from the flowers is used externally for skin care. St John's wort flowers around the summer solstice, hence its traditional links to midsummer.
