I have developed a sensitivity to black fly bites over the last couple years. When bit, the area becomes very red, hot, swollen, painful and then it begins to weep at the bite site. This week I decided to apply Neem Salve to the bite areas immediately and within 24-48 hours the symptoms were about 80% better. Previously, it would take up to 10 days to reach the same level of comfort. I am grateful for yet another Earth to Body product.
