If you can find it, asafoetida is a spice that tastes great in bean/lentil dishes and helps with gas. My grocery store sells it in bulk. Smells like complete ass (sulphur) but tastes good and helps with gas.

Antiflatulent. Asafoetida reduces the growth of indigenous microflora in the gut, reducing flatulence.[9] In the Jammu region of India, asafoetida is used as a medicine for flatulence and constipation by 60% of locals.[10]

A digestion aid. In Thailand and India, it is used to aid digestion and is smeared on the abdomen in an alcohol or water tincture known as mahahing. Asafoetida in this tincture form was evidently used in western medicine as a topical treatment for abdominal injuries during the 18th and 19th centuries; although when it came into use in the West and how long it remained in use is uncertain. One notable case in which it was used is that of Canadian Coureur des bois Alexis St. Martin, who in 1822 suffered a severe abdominal injury from an accidental shooting that perforated his right lung and stomach and shattered several ribs. St Martin was treated by American army surgeon William Beaumont, who subsequently used St Martin as the subject of a pioneering series of experiments in gastric physiology. When St Martin's wounds had healed, there remained an open fistula into his stomach that enabled Beaumont to insert various types of food directly into St Martin's stomach and record the results. In his account of his treatment of and later experiments on St Martin, Beaumont recorded that he treated the suppurating chest wound with a combination of wine mixed with diluted muriatic acid and 30-40 drops of tincture of asafoetida applied three times a day, and that this appeared to have the desired effect, helping the wound to heal.[11]
