Here is something else.
A really good long time friend of mine was telling me that her adopted mother is Lebanese. She said that Tanini is excellent for opening and clearing the lungs and would be great for me to take for my asthma. If it will work for Asthma I can see promise for covid. Here is what it says about it that caught my eye even though it has a lot of health benefits:
Tahini is a mineral powerhouse which boosts and strengthens the immune system. The high zinc, selenium, iron, and copper content in tahini help fight viral and bacterial infections. Zinc, iron, and copper facilitate the production of germ-fighting white blood cells. Selenium has the ability to support enzymes in the body so that they can release antibodies.

I never knew that about tahini - very interesting! I love hummus, which is ground chickpeas and tahini, and eat a lot of it.
