According to Ayurveda, sugarcane juice helps strengthen your liver and is thus suggested as a remedy for jaundice. Jaundice is a condition where you find yellow pigmentation of the skin and membrane due to elevated levels of a substance known as bilirubin in the bodily fluids and is triggered by poor functioning liver. What sugarcane juice does is replenish your body with proteins lost and nutrients that it needs to recover quickly.
Ayurveda also suggests that 'sugarcane juice exhibits laxative properties thereby improving bowel movement and relieving constipation'. Sugarcane juice also has alkaline properties which mean it's good for treating acidity and stomach burns.
It has a low glycemic index (GI) so it comes highly recommended for diabetics. A study showed that drinking sugarcane juice did not alter the blood glucose levels of diabetics drastically but you should check with your doctor before you start to drink some of this yourself.
