Yes, it is true the PUFA filled seeds raised my temperature from 97.1 to 98.6! One idea I had is I know manganese is important for thyroid and many microbes LOVE manganese. Black seed has high antimicrobial activities so maybe I was finally able to utilize the manganese? It's also highly relaxing. I take some seeds chew on them and let them sit in my mouth for a few minutes then spit them out. Kinda a opiod like feeling which I know is a huge no no, but they obviously raised my metabolic rate. It also had some direutic properties getting rid of the sodium fluff... reminiscent of progesterone. Anybody have a clue why these raise my temperature so much? And you may not believe me but try it and tell me different.
