What first aid items are "medical expenses" for IRS 502 purposes

I have some money in a health savings fund and want to see if any of it can be used towards first aid items. It appears that at least bandages are covered but what about quick clot/kerlix/tqs. Any other useful items that I can purchase with these funds?

Thanks!

If in doubt, use those funds on boo-boo kit items. Alternatively, OTC medications that are also helpful would be worth a look.

I tried to use mine to buy GOOD nitrile gloves, and that was a no-go. I found an IRS listing of the approved items. I can't remember the page/form/whatever, but it's on the IRS website.
