There are some of us who cannot eat nightshades like tomatoes, potatoes, eggplants, peppers and cannot be around people who smoke because their exhale is full of the nightshade residues, since tobacco is a nightshade. This causes arthritis, phlebitis, neuritis, and other 'itis' pains.
The only way I can teach yoga each week to hundreds of 3 and 4 year old children at the YWCAs all over Miami-Dade County is that I am very careful about not using nightshades.
One splash of tobasco sauce (and I didn't put it on my food), like I experienced at a conference two weeks ago, and I am crippled for days.
Peace and Love Be With You,
