If you want to buy a cayenne and ginko combination, Dr. Schulze sells a combination called "Brain Formula."

Here is a link to the page of his online catalog where you can get that.

If you want just plain cayenne tincture from Dr. Schulze , here is the link.

Dr. Schulze does not sell a plain ginko tincture, but you can get a plain ginko tincture from www.blessedherbs.com as well as a plain cayenne tincture.

I hope that helps. If you want to, you could make your own as well.
