Where To Buy Jamun?

We get fresh jamun, jamun juice and jamun seed powder in the markets. I would suggest making your own jamun juice at home for best results as the juice we get from the markets are loaded with sugar and preservatives.

Jamun Dosage:

Jamun seed powder can be taken in the dosage of 2 to 5 grams for treating diarrhea and stomach ulcers.

Jamun Side Effects:

Jamun has very very low toxicity and rarely causes any side effects if had in moderation. But over consumption can cause bloating. Jamun fruit is to be sold cheaply everywhere when I was younger but now it is very expensive to buy in the markets, one kilo costs around 220 rupees as the trees are not cultivated much….
