Mimosa pudica is a member of the Fabaceae family. It is diffusely spreading, slightly woody annual or perennial herb. The stems branched, up to 1 m high, sparingly prickly and with numerous bristle hairs bent downward. The leaves alternate and bipinnate, very sensitive, both the pinnae and leaflets falling when touched. Pinnae usually 4, subdigitate at apex of bristly petiole. Two lance-shaped stipules at base of petiole. The leaflets narrowly oblong in shape, sharply pointed, sides straight, measuring 1-1.5 cm long, sessile, covered with fine bristles. The flowers numerously arranged in heads nearly 1 cm in diametre, long peduncled, solitary or 2 or 3 in each axil. The flowers pink in colour while the stamens 4 in number. The pods flat, slightly curved outward or backward, numerous, measure 1-2 cm long, made up of 3 to 5-seeded joints that open at maturity and fall away from the persistent armed sutures with hairs numerous, weak, spreading and yellow-white bristles. The seeds obovate in shape, measuring 2 x 1.5 mm and brown in colour. The seedlings emerge as a single stem bearing cotyledons and the once-pinnate first true leaf; subsequent leaves bipinnate.

In traditional Indian medicine M. pudica is an important ingredient in the treatment of haemorrhoids, diarrhea, persistent dysentery. For haemorrhoids it is incorporated in an ointment preparation. Decoction of the leaves help relieve diarrhea. 
The roots of M. pudica are used to treat bronchitis, asthma and productive cough.

As a post partum treatment Mimosa pudica is prescribed by the midwives of Malaysia to help cleanse the external genitalia and causes the shrinkage of the vaginal canal. The Nicaraguan and Mexicans make use of the plant to stop excessive menstrual bleeding.   
A bath of the decoction of the whole plant relieves insomnia. The Mexicans and the Vietnamese use the decoction of the dried leaves to alleviate depression. The drug is also used to treat convulsions and neurasthenia.  
A decoction of leaves or roots acts as a diuretic and is used to treat stones in the urinary tract. The roots in the form of a decoction are used to treat various renal and urinary tract diseases including gonorrhea, dysuria, lithiasis and haematuria. It is also used in the treatment of hydrocele.    
The leaves have great value in inflammatory diseases. A paste of the leaves is rubbed over glandular swellings, applied over cuts and wound, sores, ulcers and herpes zoster. The decoction of the leaves can treat acute conjunctivitis, high fever in children, coryza and bad effects of cold including influenza and acute otitis.

Restless children are bathed with a decoction of the plant. To firm up the breast the Malay community made use of the plant pounded with two Areca catechu fruit and some salt. This is applied nightly. 
One of the traditional uses of M. pudica is as an antifertility medicine. In Assam the roots of M. pudica is used as a temporary birth control medicine. Study observed that the oestrus cycle pattern in female rats were altered. This was evidenced by the absent of nucleated and cornified cells, smear was chacterized by leucocytes only as in dioetrus and there was significant reduction in the number of normal ova and a significant increase in the number of degenerated ova. Study confirmed this effects when they found that the methanol extract of dried roots could prolong the oestrus cycle, disturbs the secretion of gonadotropin hormones and decrease FSH level in proestrus and oestrus stages.
Study could not demonstrate any effects of M. pudica on either preventing stone deposition or dissolving performed stones.
In the screening study of six Jamaican medicinal plants against filiariform larvae of Strongyloides stercoralis, Study found extracts of M. pudica could inhibit the larvae within 1 hour of exposure.
Reports found that the aqueous extract of the roots of M. pudica had significant inhibitory effect on the lethality, myotonicity and tested enzyme activities of venom of Naja kaouthia. Anothe study found that amongst the enzymes inhibited by the aqueous extract of M. pudica root included hyaluronidase and protease from Indian snake venoms (Naja naja, Vipera russelii and Echis carinatus)
Decoction of the leaves of M. pudica was able to inhibit convulsions induced by pentylentetetrazol and strychnine but not against picrotoxin-induced ones. It also antagonized N-methyl-D-aspartate-induced turning behavior.
Study found that aqueous extracts of dried leaves of M. pudica was able to reduce the immobility in the forced swimming test and increased the rate of reinforcers received in the DRL-72s test. These results is suggestive of the presence of antidepressant effects in rats.
Study found that by giving the ethanolic extract of leaves of M. pudica at a dose of 250mg/kg to mice they could produce a significant hypogylcaemic effects.
Wound healing activity
Study on the wound healing activity of aqueous and methanol extracts of roots of M. pudica. They found that these extracts possesses significant wound healing properties probably due to the high phenol content in them.
Antiasthmatic activityThe ethanol extract of the whole plant of M. pudica showed inhibitory activity on asthmatic attack induced by ovalbumin in BALB/c mice. It was found to inhibit HMC-1 cell migration induced by stem cell factor and blocked the release of monocyte chemotactic protein-1 (MCP-1) and interleukin-6 (IL-6) in EoL-1 cells. There was also suppression of Leukocytosis, eosinophilia and mucous hypersecretion, features common in asthma.
