The strawberry is one of the most widely consumed fruits in the world, and it can be eaten in a variety of different ways. The strawberry leaf is known to have diuretic purposes, while its tannin content makes it beneficial in treating inflammation, kidney ailments involving stones, urinary tract issues, and liver disease.
One cup of strawberries contains just 43 calories and more than 100 percent of your recommended daily vitamin C intake. Strawberries go badly very easily, so it is recommended that you do not wash or cut them until you’re ready to eat them.
The medicinal parts are dried leaves collected during the flowering season, the dried rhizome, and ripe fruit.
Flower and Fruit
The small white flowers are arranged on a repeatedly bifurcated pedicle. They are usually androgynous. There are 5 sepals and 5 petals. The sepals are triangular, pointed, or appressed pubescent. The petals are oribicular or ovate, glabrous, and pure white. There are 20 stamens and numerous ovate, glabrous carpels and a style at the side. After flowering the receptacle turns into a fleshy false fruit. The receptacle is 2 cm long, ovate, globular or clavate, and red when ripe. The nutlets are ovate, 0.8 to 1.5 mm long, brown and matte.
Leaves, Stem, and Root
The perennial, herbaceous plant grows from 20 to 30 cm high. The rhizome is cylindrical, horizontal, or crooked and thickly covered with the residual dead leaves and stipules. Long runners grow from the axils of the basal leaves. The stem is erect and is slightly longer than the basal leaves. The cauline leaves are trifoliate and roughly serrate from the first quarter upward. The petioles are very long and, like the stem, have patent hairs. The stipules are lanceolate, long-acuminate, entire-margined, reddish brown, glabrous above and hairy beneath.
Found in almost all of the temperate zones of Europe and Asia.
Strawberry leaf consists of the dried leaf of Fragaria species, mainly Fragaria vesca. The leaves are collected in the wild and air-dried in a shady place.
