Mimosa pudica, also called sensitive plant, humble plant, touch me not, shame plant, is a prostrate or semi-erect subshrub plant native to Asia and the Pacific Islands, and in the pea family (Fabaceae). As its name implies, the mimosa is a very interesting plant, and its leaves will fold up when you gently touch them. Many people like this shy plant and keep it at home as an ornamental

A team of researchers led by Takaye Tsuchiya of Sophia University in Japan has solved the mystery of the closed motion of the mimosa plant: cells of the plant are supported by tiny net-like proteins called actin. When closing motion occurs, the phosphoric acid of kinetoprotein is shed, and as long as the mimosa plant does not absorb the phosphoric acid shedding compound, it does not change when touched. Tsuchiya points out that when the kinetoprotein bundles are spread apart, the cells are destroyed, resulting in water escaping and a closed motion. Kinetoprotein is commonly found in muscle fibers of animals and is associated with muscle stretching and contraction, also found in mimosas pudica.

Is mimosa pudica poisonous?

Mimosa is slightly toxic and contains a substance called mimosaine that can cause hair to turn yellow or even fall out. Mimosa is harmless during the day but releases toxins at night because it can’t photosynthesize. Mimosas need strong light, indoor light can not meet its growth needs. Therefore, we suggest that it is best to keep mimosa outdoors in order to avoid harm to the body.

The most common is the poisoning caused by cattle eating mimosa without thorns, manifested as depressed spirit, grinding teeth, panting, dyspnea, and neurological symptoms, edema, and generally more in winter. In addition, due to the content of mimosa, camels, horses and other edible mimosa will appear molting phenomenon.
