By NS Desk | Herbs | Posted on :   12-Dec-2020

The Java plum or Jamun can have and can be called numerous names. But the name that I would like to call is "Grown Grapes." They resemble the grapes in a way. One of the reasons why people long for summer is for all kinds of summer fruits. Mango and Jamun are of best interest to everybody. Java plum has a combination of a sweet and sour taste. This gives a reason for the fruit to be unique. Java plum is such an awesome and effective fruit as it has multiple medicinal values. The consumption of Jamun can be done in different ways. Some like to have it in juice form, and some will like to eat it in the fruit form itself. People with diabetes would love to eat this fruit as it helps in controlling the sugar levels. The fruit also helps obese people in weight loss. Though it has a lot of positive qualities, it has a few negatives as well. A huge amount of consumption of Jamun is not advisable as it leads to constipation. Anything and everything has to be consumed to a limit.

The Etymology of the Word “Jamun”

The word Jamun originated in the early 19th century from the  Hindi word Jãmun for   Syzygium Jambolanum, commonly known as Black Plum. This comes from the Jamun tree. 

Historical Uses of Jamun

The leaves, seeds, and fruit of Jamun were used to treat diabetes, asthma, skin allergies, diarrhea, inflammation, ulcers, etc. The Jamun plant is enriched with anthocyanins, ellagic acid, isoquercetin, kaempferol, and myricetin. All these rich contents help to cure a lot of problems.

The Jamun fruit was well known in folk medicine. The fruit is known to contain a high range of antioxidants. The tree, seed, and fruit of the plant were still known to be used in medical practice.

This also helps one with weight loss. Many obese people try to include this fruit and its various forms in their diet schedule. This helps them by eliminating the excessive fat segregated in their body.

Benefits of using Jamun in Ayurvedic Treatment

It has also been tested on humans, and the results have amazed everybody. It has lowered and maintained sugar levels in patients with diabetes.

The kashaya or astringent property and grahi or absorbent property in the seed powder controls atisar.

It is because of Sita (cold) and Rogan (healing) property.
