Syzygium Jambolinum To Stabilize Blood Sugar
How This Helps
Syzygium jambolanum is a tree commonly called the black plum, native to India. Its seeds are used to extract the medicinal tincture which is rich in alkaloids which help normalize blood sugar levels in diabetics. The most important active components that exert the anti-hyperglycemic action are jambosine and glycoside jambolin or antimellin. It has not been clear which alkaloid exerts what action, but collectively these halt the diastatic conversion of dietary starch into sugar. 
Science and Research
Type 2 diabetes is a major endocrine disorder characterized by hyperglycemia or raised blood sugar levels. Apart from genetic factors, obesity, family history, mental stress and sedentary lifestyle contribute to the development of diabetes. Homoeopathy offers medicines with substantial glucose lowering properties making it a much preferred system of medicine to treat diabetes. It aids the mind to combat stress that can help minimize the psychological element as well as attend to the physical component of diabetes.
Extensive research has revealed that elevated glucose for a long period causes protein glycation leading to advanced glycation end products - the major cause of different diabetic complications including retinopathy (eyes), neuropathy (nerves), and nephropathy (kidneys).  Syzygium jambolanum has the pharmacological potential of interrupting this process of glycation thereby protecting the organs against the injurious effects of diabetes. 
History reveals that in the pre-insulin era when there were no specific modalities of treatment, Syzygium jambolanum was used extensively to treat hyperglycemia. Syzygium jambolanum has been found to reduce blood sugars as well as sugar in the urine rapidly without any adverse reactions. 
In addition to the glucose lowering potential in Syzygium jambolanum, the ellagic acid content of the seeds also contributes in lowering blood pressure by around 34.6%.  A blessing in disguise!
25 drops of the mother tincture diluted in about half a cup of water should be taken 3 times a day for at least 3 months for the desired results.
Note: For patient specific treatments and dosage, always consult with a homeopathic doctor before beginning treatment.
