Replaced ineffective 4 gas relief capsules that were quite costly with just one Fennel capsule. The first time I took one my body deflated but the next time, after eating half a cabbage I didnt suffer at all so I know this natural remedy works. I used to keep Gas-X in business with my purchases alone, but now I just dust those full boxes off. I only take one capsule before a particularly notoriously known gas producing food. Hope it gets back in stock.
