What medical supplies do I need to bring to other places?

Correct the above answer: Band-Aids are Band-Aids, and Huoxiang Zhengqi is not "He". In my outdoor first aid kit, gunpowder, water purification tablets, surgical blades, band-AIDS, butterfly bandages, triangular towels, two short sticks, iodine, alcohol, antiallergic agents, laxatives, cefradine capsules, tourniquets, rescue pills, adrenaline (medical professionals) and so on.
