The wife and I made homemade vapor rub, similar to Vick’s.
1/2 cup of coconut oil
1 tablespoon of beeswax (optional)
Essential oils of lavender, camphor, peppermint, rosemary, and eucalyptus
In a double boiler, melt the coconut oil and beeswax. (The beeswax is only to make it thicker.) After everything is melted, add 5 drops of each oil. After it cools, test it out on the inside of your wrist. If it burns, re-melt and add more coconut oil. If not strong enough, re-melt and add more camphor, lavender and eucalyptus. Adjust to suit your needs.
The odor of the coconut oil will mask the odor of the essential oils, so your nose is not a good indicator of strength.
This works very well, with the added benefit if being safe ingredients. There is some debate about the use of petroleum jelly and it’s effects on your body.
The initial cost of the ingredients is high, but should average out to be cheaper than store bought. We use all of these items regularly, so this fits in with the rest of our purchases.
