Harm score: 1 (Natural substances)
Sedum acre (Sedum acre), also known as sharp stonecrop, is a succulent plant belonging to the family Sedum acre. Its scientific name, Sedum acre, is related to the Latin word 'sedum', meaning a sessile plant - in the case of the sharp stonecrop this refers to its ability to grow in a wide range of terrain. It is an undemanding evergreen herb that is characterised by its dense spurs and bright yellow flowers. It is native to Europe, but has been introduced to North America where it has become an invasive species.
The sharp-leaved stonecrop is most commonly used in horticulture as an ornamental plant because of its hardiness and beautiful flowers. In some countries it is also used as fodder for sheep. The plant is also important in medicine, where it is used for its antiseptic and diuretic properties. However, care must be taken as it can cause skin or digestive tract irritation if used improperly. Furthermore, although the sharp stonecrop was formerly used in the kitchen as a spice, it is now discouraged due to its potential toxicity. On the other hand, St John's Wort extract is found in some cosmetic products, especially moisturizers and sunscreens, where it uses its hydrating properties.
