Rock sugar is widely used in India with fennel seeds as a mouth freshener after the meal. I went to a restaurant for lunch today where they served it after they cleared the table. I was so curious and I tried. That was my first time chewing mouthful raw, uncooked fennel seeds. So Fear Factor one..
From (here) - Fennel (Foeniculum vulgare) is a herb that has long been used as a remedy for flatulence, upset stomach and intestinal cramps in Ayurveda, Mediterranean medicine and other healing traditions. Fennel promotes gastrointestinal motility, thus relieving gas buildup in the intestines.
Reading that makes me feels a bit better. I actually did something good for my intestines today.
