Obviously as martial artists we hit things, and something I have noticed I have incorporated more and more bag work into my training over the last year, is how often I end up with bruised/swollen knuckles. I am not bothered so much by the aesthetics of having slightly puffy/purple-y knuckles, as I am by the fact that I then can't hit anything for 48 hours or so afterwards if I want the knuckles to actually recover/not go straight back to their swollen state after a few blows. Of course a more immediate solution would be to just train with gloves, but given I am only getting in around three 30 minute bag sessions a week I can't see myself doing any permanent damage and would quite like my knuckles to just (continue) grow(ing) a bit stronger.
I have been trying helichrysum oil after some advice from a pharmacist following a particularly vigorous training session some months ago, but have found that it just seems to hide the bruising/reduce swelling more than aid with the recovery (and at £15 for 5ml of it I now know why the pharmasist was so keen to sell me it!). I know that people in chinese martial arts supposedly use something called 'dit da jow', but I don't know much about it and lots of the info on it on the web seems to be contaminated with "chi magic" type stuff so it is difficult to know whether it is just a new snake oil or something that is actually effective.
In any case, I thought I would ask you all in all your wisdom if you have any particular advice/experience on the matter. What do you all do with your bruised knuckles beyond just letting them rest?
