MEDICINAL PROPERTIES AND USES :   
The stem is bitter astringent, acrid, thermogenic, anti-inflammatory, anodyne, digestive, liver tonic, emetic, diuretic, Stomachic, stimulant, anthelmintic, laxative, cardiotonic, expectorant, antipyretic and uterine tonic. It is useful in inflammations, hepatosplenomegaly, dyspepsia, constipation, jaundice, haemorrhoids, strangury, renal and vesical calculi, helminthiasis, cardiopathy, cough, asthma, bronchitis, intermittent fever, amenorrhoea, conjunctivitis & leucoderma. The fresh leaves when chewed have the remarkable property of paralysing the sense of taste for sweet and bitter substances for sometime.

In the case of the far more prevalent type 2 diabetes--also known as noninsulin-dependent diabetes--research findings indicate that the use of gymnema may improve blood sugar control and result in the need for smaller doses of oral diabetes drugs to control the disease. However, it's critical that people with this disease don't abandon proven ways to manage it, from a healthy diet to regular exercise and medications when needed. 
   
        
CULTIVATION AND PROPAGATION :

SOIL AND CLIMATE
   
The plant grows in a variety of soil and agro-climatic conditions in tropical and sub-tropical regions up to 600 m. 
   
        
NURSERY RAISING AND PLANTING

Mature seeds are collected during October-December and sown in poly-boxes/bags or small plots in nursery. The raised seedlings are transplanted in field during February-March. The plant grows well with the on-set of rainy season. The climber is given proper support for its better growth and development. It can also be planted in between trees as intercropping. The plant can also be propagated through cuttings and planted during rainy season.

   
   
WEEDING AND HOEING   
   
Periodical weeding and hoeing is required, particularly during and after rainy season.    
        
IRRIGATION

Periodic irrigation as and when required may be done weekly/fortnightly.

   
HARVESTING/POST HARVESTING OPERATION    
After one-year, leaves are ready for harvesting. The leaves are usually collected during October-February and are cleaned and dried in shade. The roots are collected during summer and are cleaned, washed and cut in to pieces and dried.


   
        
CHEMICAL CONSTITUENTS

MAJOR CONSTITUENTS

Gymnemic acid
   
        
OTHER CONSTITUENTS

Gymnemic acid I, II, III and IV are isolated from leaves and their structure elucidated. Gymnemagenin a hexahydroxy triterpene was isolated from the plant.


   
        
ACTIVE CONSTITUENTS

Various fractions obtained from the plant leaves show Antieurodonic effects.

   
        
SUBSTITUTE/ADULTERANTS

Pieces of sapwood are the main adulterant. These are lighter in colour and devoid of any odour but are more often artificially impregnated by sandalwood oil. Exhausted wood shaving and sawdust after distillation of oil are also mixed with the commercial material.
