Thank you all for your helpful suggestions.  My sore cleared up very rapidy -- 
in 3 days crusted over and scab fell off.  Diet changes to try to speed healing 
were: stopped eating all seeds and nuts; added additional vitamin C 
supplement; added a supplement by Quantum Health called Super Immune+ 
Power Formula:  3 capsule serving contains 1,500 mg. Lysine; 200 mg 
Astragalus Root and 100mg Olive Leaf Extract.  I took 1 capsule 3 or 4 times a 
day.  Issue is this -- to make sure the virus is really gone, I've continued 
taking the capsules even though the cold sore is healed.  I've been 
experiencing unusual fatigue and nausea -- can this be continued die-off 
reaction?  I've heard that olive leaf can cause die-off reaction but the amount 
I'm taking is so small -- 200 mg.  Anyone out there knowledgeable about herbs 
know if perhaps there is  a synergistic effect with the astragalus and lysine 
that makes even a single capsule (1/3 serving) potent in it's anti-viral action?  
This AM before exercise I took 1 capsule on empty stomach and about 30 
minute later felt nausea, fatigue, achey. Thoughts?
