🌿 Introduction
Jamun (Syzygium cumini), also known as Indian Blackberry or Java Plum, is one of India's most treasured medicinal fruits. Its deep purple colour comes from powerful anthocyanin antioxidants that protect cells against oxidative stress. In Ayurveda, almost every part of the Jamun tree—including the fruit, seeds, bark and leaves—is used for supporting digestion, blood sugar balance and overall health. The fruit is low in calories, rich in vitamin C, potassium and polyphenols, making it an excellent seasonal fruit for healthy living.
