@Jabeen, coriander is actually well known for its blood purifying properties and hence even women with new born babies are encouraged to eat fresh coriander in various preparations. Do try the remedy, I am sure it will help, and if you can get fresh neem leaves, add them too with mint, coriander and fenugreek. It will give added benefits of shining skin.
@ Kalyani
I think i should try the remedy you have suggested for the acne as they are easily available ingredients. I am though surprised to learn that coriander leaves can take care of the marks left by pimples. Here it is believed that coriander is not good for scars and other marks. In fact, traditionally women who have delivered babies are prohibited from eating coriander leaves for around three months after birth
