St John’s Wort, scientifically known Hypericum perforatum, is a perennial plant native to Europe that has spread throughout the world. It belongs to the Hypericaceae family and can be recognised by its bright yellow flowers and perforated leaves. Traditionally appreciated for its medicinal properties, particularly in the treatment of depression, St John’s Wort also has applications in a variety of industries beyond nutraceuticals. Its extracts are used in cosmetics for their anti-inflammatory and healing properties, while the plant itself can be used in landscaping for its ornamental beauty and in natural dyeing for its colouring properties.
