Which Cannabis oil do you need for -

Hives

Infused Drops

5 drops on the underside of the tongue mornings and lunchtime

Detox Fuel

take 1 teaspoon twice daily with detox tea

Caps No. 5

take 1 at night AFTER dinner (no hot drinks for 30 mins)

Canna Balm

Rub on affected area 2 or 3 times a day

The Canna Balm will probably do the trick but I suggest you go for the full protocol above to make sure it is out of your system.
