Bloating & Trapped Wind
One of the best ways to move trapped wind is with any aromatic herb or spice. We call these carminatives in herbal medicine. In Ayurveda, it moves apana vata, moving the energy down and out.
CCFT - is a common remedy of cumin, coriander and fennel, you can make a tea with all 3 or just fennel on its own.
Half a tsp of each in a teapot or cafeteria, fill with hot water, add a lid to ensure the volatile oil and medicines do not escape in the steam. There are no specific amounts really, you can add more water if you want the taste weaker.
Peppermint is also a good remedy but best avoided in pitta conditions and people, too much heat, acid reflux, gastritis or gut inflammation.
