Nigella Sativa (Black Cumin) has analgesic and anti inflammatory effects. N. Sativa is also known to be antibacterial.
Lightly massage 1 drop of N. Sativa oil to the mosquito bite - re-apply the oil throughout the day. After the oil application try to keep the bite clean, this means no scratching. The following day my bites are reduced in size and do not itch.
