Cat's claw should not be used if you are taking anti-ulcer medications or if you are pregnant or nursing.

L-lysine is often used to treat or prevent migraines and is not otherwise commonly associated with headaches.

One factor often ignored by people using natural treatments is that they make seem initially to have aggravated the condition that they were taken to treat. This is part of the healing response and reflect's the body's "surprise" at having readily available nutrients that it lacked before.

In response, it can over-compensate and work a little too hard initially on the problem. If this happens, it is usually short-lived and resolves by itself within a few days.

If symptoms persist, you should sonsult the person who recommended the supplements to you and/or visit a naturopathic physician. Natural treatments rarely have side-effects, but there is always a slight risk of contamination (as there is with pharmaceuticals), especially with bulk-manufactured supplements.
