Hi Dana,
I'd like to add to you warning about Arginine.
I have found that it causes many herpes-related or herpes-like viruses to become active; shingles, cold sores, fever blisters, etc. These are all viruses that normally lie dormant.? Eating high Arginine foods like pecans or taking Arginine supplements, can cause them to awaken and travel down the nerves to erupt on the skin in painful lesions. You are again correct in that L-lysine counteracts the effects of Arginine.?
I've also found physical, emotional and environmental stresses can also cause these viruses to awaken. Rhodiola Rosea is an adaptogen that helps the body adapt to, and overcome these stresses and causes the viruses to subside.?
It is also possible that the fungi growing on the nut skins could cause the viruses to awaken. Regardless of the cause, I take Lysine and Rhodiola Rosea supplements in the fall and winter to avoid problems.
Best regards,
Dan
