Apple cider vinegar is an astringent and will draw fluid and swelling away from an injury. Normally when you have injured yourself you think of applying ice to reduce the swelling but having recently turned my ankle twice I would have no hesitation in recommending apple cider vinegar as your first aid treatment. Due to its acidity ACV should not be applied directly to broken skin although you could apply a thin layer of vaseline to the wound before applying the ACV.
Apple cider vinegar can cause skin irritation in some cases and in that case you can dilute the ACV by as much as 3 parts water to 1 part ACV. If you have sensitive skin you may wish to do a patch test (put a small amount on a cloth or kitchen roll and leave it on the arm for 10 minutes) if no irritation occurs in that time then you should be okay.
First soak some kitchen roll or a hankerchief in the apple cider vinegar and apply to the affected area e.g. ankle, then wrap the whole ankle in clingfilm this will stop the ACV from evaporating too quickly (and keeps the smell in a bit too). This can then be left in place for up to 2 hours.
What to use Apple Cider Vinegar for:
- Stings and rashes
- Sunburn (I found this out recently when caught out by the unexpected amount of sun whilst golfing last year)
- Areas of redness and heat
