The texts of ayurveda explain the medicinal properties of sugar cane as follows

The juice of sugarcane exhibits laxative properties. It normalizes bowel movement and relieves constipation. Sugarcane juice is heavy to digest and boosts moisture level of tissues. Regular consumption of this juice increases body bulk. Cane juice increases kapha and acts as diuretic. It is aphrodisiac and helps in conditions like erectile dysfunction, low sperm count and low sperm motility. Ayurveda acharyas recommend this sweet liquid in diseases which arise due to vitiation of rakta (blood) and pitta.

It is always advisable to use clean and fresh sugarcane juice. In ashtanga hridaya, Acharya Vaghbhata strictly advises not to use the stale sugarcane juice. The sugar cane juice extracted from healthy canes has high medicinal value. The sugar cane juice which is stale, extracted from insect infested canes, contaminated with dust and mud should be discarded. Contaminated sugarcane juice causes indigestion, diseases and constipation

Fresh pure sugarcane juice is rich in natural sugars and minerals. It is an instant energizer and provides strength to body. Its medicinal properties get enhanced when mixed with juices of lemon and ginger. It helps to clean the kidneys and eases urine flow in conditions like cystitis, Benign Prostatic Hypertrophy (BPH) and urinary tract infections. It rejuvenates liver and helps in speedy recovery from jaundice.
