I know this one is the most difficult. Chew everyday 2-3 leaves of Neem. I know it sounds disgusting. Believe me, it tastes really horrible. I have done it. At last, I could not bear to chew so I started swallowing the leaves. Wash them properly before in taking them. Do not boil them. A help would be take them with honey or jaggery. And, follow it up with a glass of water. Do not worry if you vomit in the starting days. Your body and taste buds will adapt gradually to it. And, the results are too good to ignore. In take of neem leaves would clean your system internally, improve the body metabolism and toxins elimination process. It would clean your blood of impurities and as a result, give you a clear skin. It even helps you get rid of constipation and improves your immune system.
