(common name is Sensitive Plant )is a special plant of genus
is low and its stem has many prickly branches.It has compound leaves with leafstalks and leaflets.
has pink or mauve flowers form small globular heads, each borne on a short hairy stalk arising from a leaf axil (Holm et al. 1977).
occurs in warm and moist habitats.
is native to South and Central America. It has been introduced to many other regions and is regarded as an invasive species in Tanzania, South Asia and South East Asia and many Pacific Islands. (Tropical Biology Association. 2006).Figure.1 shows a

Leaves of Mimosa pudica fold
has an extraordinary 'product' that its leaves are able to fold when touched. This phenomenon is not because mimosa pudica is 'shy', it is because cells of
are stimulated and water loss. In fact, the leaves of
open during the day and close at night.

(own make,information bases in eHow.)
The ability to fold its leaves may benefit the mimosa pudica in three ways:
Folding leaves sometimes let herbivores be unappetizing.
The ability to fold its leaves that can reduce loss of water.
It is 'nyctinastic response' that the plants close their leaves when not exposed to the sun. Nyctinastic response keeps the plants safe through the night.
Video.1 shows when we touched,
its leaves would fold.

contains many chemical substances, such as norepinephrine, ascorbic-acid, and sitosterol. So, in medicine, the seeds, leaves, roots of mimosa pudica have great medicinal value. For example,
is able to be made a kind of the psychic energizer, because aqueous extracts from dried leaves of
are used to assuage depression.
also has been shown to be helpful in the reduction of blood sugar in rodents with high blood sugar, suggesting that mimosa pudica might be helpful as a diabetic treatment in humans as well( Uses of
,eHow, 2009 ).
can be hemostatic and help wound healing, such as ulcers, scrofula, and conjunctivitis. It is popular mainly for its styptic property, with which it promptly arrests the bleeding in ailments like hemorrhoids, haemoptysis in tuberculosis, menorrhagia, ulcerative colitis, dysentery and raktapitta( Ayurvedic Preparations. n.d ).
In the other hand,
also can predict earthquakes. Before a strong earthquake happened,
will atrophy suddenly, and then they will shrivel.In Japan，scientists found that leaves of
open during the day and close at night in normal circumstances, but when leaves of
open at night and close during the day, the earthquake will happen.
In ecosystem, if
forms thickset ground cover, they will prevent growth and breeding of other native plants by preventing their seeds reaching the ground and competing inorganic matter.In social, economic, and health
is one of major weeds for agricultural fields and plantations of corn, soybeans, tomatoes, upland rice, cotton, bananas, sugarcane, coffee, oil palms, papayas, coconuts, and rubber in many tropical areas( Bui, 2001 ).
contains an alkaloid that is named as mimosine(Figure.2). The mimosine is poisonous, and it is able to cause hair peeling of animals(Figure.3).

( Sensitive Plant ) is a valuable plant. Folding leaves of
is a good research topic about the plant makes reflection for enthetic stimulates in botany. In medicine, it is beneficial the treatment of some diseases, but it contains some harmful chemical matter that is against health of human and animals at the same time. So we need to be careful to use
