Arnica is used as a herbal ointment to help alleviate pain for aches, bruises,
stains and lessen anti inflammatory. It can be compared to a 5% ibuprofen gel.
The neuropathy oil adds to helping the pain scale and numbness, as a calmness
effect.
Use a small amount dime size. A little goes along ways.
Also test a small area for reactions first.
