Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Stimulant  Vasodilator

Thoroughwort is one of the most popular domestic medicines in North America[4, 213] where it is used in the treatment of influenza, colds, acute bronchitis, catarrh and skin diseases[238]. It has been shown to stimulate resistance to viral and bacterial infections, and reduces fevers by encouraging sweating[254]. The plant, however, should be used with some caution since large doses are laxative and emetic and the plant might contain potentially liver-harming pyrrolizidine alkaloids[222]. The leaves and flowering stems are antispasmodic, cholagogue, diaphoretic, emetic, febrifuge, laxative, purgative, stimulant, vasodilator[4, 61, 165, 238]. A hot infusion of the dried leaves and flowers is used as a very effective treatment to bring relief to symptoms of the common cold and other similar feverishness - it loosens phlegm and promotes its removal through coughing[213, 254, 268]. This herb is practically unequalled in its effectiveness against colds[268]. It is also used in the treatment of rheumatic illness, skin conditions and worms[254]. The leaves and flowering stems are harvested in the summer before the buds open, and are dried for later use[238]. A homeopathic remedy is made from the fresh plant, harvested when it first comes into flower[232]. It is used in the treatment of illnesses such as flu and fever[232]. Was used by Native Americans to treat malaria [301].

Very easy, the clumps can be replanted direct into their permanent positions.
