For cuts, keep some Neosporin on hand
Made up of bacitracin, neomycin, and polymyxin B, Neosporin cream is crucial in infection prevention. In pharmacological terms, the neomycin binds with ribosomal RNA, “causing misreading of the bacterial genetic code” (National Library of Medicine) while the bacitracin and polymixin B cooperate with the phospholipid components of the cells. Basically, the ingredients will work like mini secret agents to kill off bacteria and allow for the medication to get into your system effectively.

For muscle pains and bruises, try Arnica
Homeopathic medicine is not rubbing leaves on your face and chanting to Poseidon, god of the sea, though many of my pre-med friends seem to believe this is the case. Whatever the case, this stuff WORKS. I’m telling you from experience. This topical gel is extremely successful in rapidly decreasing inflammation and bruising. Alternative Medicine Examiner Brett Chandler-Finch explains that due to the ability of the herb, Arnica Montana, to stimulate “the number of white blood cells in the affected area”, it is effectively able to “process congested blood and disperse fluids in bruised and injured areas”.  You can purchase it at your nearest CVS.

Author’s anecdote: One time, it was raining and I slipped on my friend’s tile stairs outside her house (let’s consider that architectural decision for a moment). Anyway, I had a huge bruise on my lower back that I thought was never going away, but as soon as I used Arnica, the bruising started to dissipate. I saw it happen literally overnight.

For those stupid, stupid UTI’s, try Cranactin
Cranactin is a cranberry supplement that can prevent urinary tract infections. It can even stop infections that are in their early stages. Studies have shown that pure cranberry prevents bacteria from adhering to the cells in the bladder. Taking it daily or at the first signs of an infection can reduce your chances of getting a full-blown UTI. It is easy to purchase Cranactin online!

For allergic reactions, Benadryl is a must
Benadryl, otherwise known by its generic name as diphenhydramine, is an antihistamine.  In pill form, it is used to treat most forms of allergic reactions, such as swelling or itchiness. It primarily accomplishes this by blocking histamines, which would normally trigger the allergic reactions in the body. Interestingly enough, it also blocks acetylcholine, making it a common treatment for Parkinson’s symptoms. It should be taken as soon as a reaction occurs. Keep Benadryl in your medicine cabinet/box/counter! You never know when you’ll discover an unknown allergy!
Â
Author’s anecdote: I never suspected that I would have allergies to particular medications, but while in my freshman year, I received medications from the health center that caused reactions. Benadryl kept my throat from closing up, so, you know, that’s a plus.
