Wild pansy – effects and use:
Wild pansy contains flavonoids (up to 0.5% rutoside, quercetin, luteolin and scoparin), anthocyanins (violanin, delphinidin 3-glucoside), phenolic acids, carotenoids (violaxanthin), triterpenic saponins (saponaretin, saponarin), traces of oil with violutoside (methyl salicylate glycoside), mucus and tannins.
Thanks to its rutin content which plays a role in cleaning out the blood and in metabolism, wild pansy has a diuretic effect (along with urine harmful substances are expelled) and therefore it is used in treating frequent and painful urination. The rutin facilitates vitamin C absorption, prolongs its activity in the tissue, reduces the permeability of capillary walls, in turn counteracting blood vessel fragility. In some circumstances, flavonoid compounds reduce the cholesterol level in blood plasma and throught that delay the development of atherosclerosis in blood vessels.
The herb also acts as a diaphoretic, facilitates the removal of metabolic waste and has a minor expectorant effect. It has mucolytic properties. Herb decoctions and infusions are used internally mainly for skin conditions (acne, eczema) and upper respiratory diseases.
Externally, decoctions can be used for throat gargling, poultices and baths for various rashes, but can cause allergies for people with sensitive skin. The herb is more effective when combined with roots, as they contain more saponins.
In his herbarium from 1597, John Gerard cited the following medical opinions relating to the herb: wild pansy is effective for treating convulsions in infants, excellent for lung infections, good for treating scabs, itching, ulcers. Wild pansy tea was used to lower fevers. The herb also helped as a laxative, expectorant and sedative. It was used to rid the body of any toxic substances.
