St. John's Wort Oil works

Apply St. John's Wort Oil, but because it is an essential oil, it is very concentrated so only a drop or two is needed. It contains tannins (which dry up a cold sore) but it is not a pain killer (even though it seems to calm the nervous system and thus decrease the sensation of pain). It is also anti-inflammatory and antiseptic, and may be applied directly on areas where there is pain or inflammation.

I you suffer from cold sores, like I used to, you can take L-Lysine , except if pregnant or nursing consult your doctor. I take two 500 mg tablets in the morning on an empty stomach and should take that amount at night, but often forget. I have had only one episode in the last year and then when I took my evening dose too it never became "full blown" and disappeared quickly.

As soon as you realize you have a cold sore coming on, apply Witch Hazel to it with a Q-tips cotton swab. It will immediately stop the process and prevent the spread of the blisters. Apply Witch Hazel frequently, and healing time is shortened to a fraction of normal.n
