"Can you use this for a variety of conditions?"
Honestly, just about anyone who has a painful either in their body (muscles, joints, feet, etc) or on their skin could benefit from trying a topical! Most folks apply it directly where it hurts and I recommend also applying at the source of the pain – so for instance, you may have a sore arm that originates in a pinched nerve in the neck. I would apply Sweet Releaf to both the arm and the spot in the neck where pain originates. For skin conditions, even mosquito bites!, apply directly to the spot & repeat as necessary on a daily basis for a few days to realize the full effect it can deliver.
