Garden bean

Phaseolus vulgaris, also known as garden bean or green bean, is a plant from the genus Phaseolus within the legume family (Fabaceae).

Phaseolus vulgaris is an annual climbing plant that can reach a height of up to 4 m (pole bean) or between 30 and 60 cm (bush bean). A characteristic feature of the garden bean is the sleeping movement of its leaves. These are made possible by fluctuations in the cell sap in the leaf and pinnule joints. Therefore, the leaves drop in the evening and 6 o'clock and rise at 6 o'clock in the morning.
In addition, the plant excretes water droplets through glandular hairs.
The flowers are pollen butterfly flowers with a pencil-brush folding mechanism. The fruits of the plant are its pods. The garden bean blooms between June and September.

Naturopathy: Phaseolus vulgaris is the parent plant of Phaseoli fructus sine semine.

Cosmetics:

• Phaseolus vulgaris extract is used in cosmetic formulations. The extract acts as an absorbent and viscosity regulator (increases or decreases the viscosity of cosmetic products).

The beans of the plant contain phasine, a polypeptide of glutamic acid, tyrosine, lysine, argingine, alanine and causes the toxicity of raw beans. The lectin is destroyed when heated.
