Coriander is the seed of the Cilantro plant. The plant is Cilantro, the seed is Coriander. I had migraines for decades, since I was about 16. It was a misery that put me in bed with a bag of frozen peas on my head until I could go to sleep and "sleep it off". I would wake up with my whole head sore from the pain.
I read all of Hulda Clark's books and she said that migraines are caused by a microscopic wormlet called Strongyloides, commonly called threadworm. Horses and cats are their preferred hosts, and we get the worms from them. Women get migraines much more often than men, and its probably because we associate closely more often with cats than men do.
Dr. Clark said that Coriander would kill them and stop migraine headaches. I found some corroboration for this theory in some ladies who live in India and Pakistan. They take it in tea form and it dispels migraine for a long time. Its a common remedy there. I tried it and my migraines stopped.
If I am reinfected by being in close proximity to carrier cats or horses, the migraines will begin again. A couple of days of coriander tea, and goodbye migraines.
