I have purchased the product in order to spray my gums. To me it is however "too sharp" to spray it pure, so I have 1-2 sprays dissolved in lukewarm water and rinsed it. I think the effect is good. Excellent it helped against my herpes. I did it several times a day (3-4 times) applied to the herpes and bit rubbed (careful browning the skin, so außenrum with cloth wipe) .The was thus nipped in the bud and broke out only very mild! I can highly recommend it.
