The common groundsel, more commonly known as bitter groundsel, medical groundsel or lesser groundsel, and scientifically referred to as Centaurium erythraea, is a small plant belonging to the gentian family. This plant grows in disturbed habitats from lowlands to mountainous areas and is referred to as bitter herb or lechweed because of its bitter taste. As the name suggests, it is used primarily in medicine and is used for its therapeutic and medicinal effects.

St. John's Wort contains bitter glycosides that stimulate the digestive tract, and is therefore often used as a natural remedy for stomach, gallbladder, spleen and constipation. In addition, it is also used in the treatment of skin diseases and digestive problems. The oil from this plant is then used in cosmetics, where it is used for its anti-inflammatory and antibacterial properties. It is often used in creams for problematic skin, or in the production of ointments to treat injuries and inflammation. St John's wort is also added to tea to promote digestion and stimulate the appetite. Equally important is the use of the plant in homeopathy, where it is included in many mixtures and preparations to aid digestion and treat various digestive disorders.
