Phase 4 trial of a traditional Chinese medicine

A few weeks ago, I noticed a few reddish splotches on my midsection. They weren't raised or itchy, so I figured they were just bruises (you know how much I frolic about). But they didn't go away. In fact, they've slowly multiplied across my body. (to clear up any over-exaggeration, I really only have about 15 spots)

Keeping it rated PG, here's a photo of one splotch on my arm:

I've tried figuring out the cause, but I'm not allergic to anything (thanks for the genes and upbringing, mom and dad!). It very likely could've been bed bug bites from Jiuzhaigou. However, they aren't irritated at all, I don't see any bite sites, and I think a few developed weeks after Jiuzhaigou. I am getting pretty old, but I don't think age spots should set in this young.

Anyway, I sent above photo to my fam, and I was recommended antihistamine and hydrocortisone. An overnight benedryl didn't help, so I visited the pharmacy on campus with lab mate Jie.

No hydrocortisone- apparently you have to go to a doctor for that (maybe they thought I meant cortisone shots?). So after some fun translation games, we settled on a traditional Chinese medicine.

my tube 'o TCM with lab notes in background. I'm so studious.

I really have no clue what this is, except that it smells kinda like icy hot... which paradoxically makes the splotch itch (or is it "ironic"? someone text Alanis Morissette for me). Also, the pharmacist said "no spicy food", but considering my addiction fondness for gong bao ji ding, I'm not sure how great my patient compliance will be.
