Turmeric
Turmeric is a common spice that comes from the root of Curcuma longa. It contains a chemical called curcumin, which might reduce swelling.

People commonly use turmeric for depression, hay fever, and osteoarthritis. It is also used for asthma, diabetes, and many other conditions, but there is no good scientific evidence to support most of these uses. There is also no good evidence to support using turmeric for COVID-19. Don't confuse turmeric with Javanese turmeric root or tree turmeric. Also, don't confuse it with zedoary or goldenseal, which are unrelated plants that are sometimes called turmeric.
