I'm a modern gal so it's a little shocking that people are going back & finding value in old ways like leeches & cupping. Cupping is a simple technique that involves pressing a suction cup into the skin. A recent experiment found that rats injected with SARS-CoV-2 DNA, which on its own quickly degrades in the body, followed by moderate suction had an immune response 100 times stronger than injection alone. This matters because vaccines that don't require refrigeration are easier to distriute in poorer countries, & if they can be more effective with a simple technique like cupping, all the better for everyone.

This is part 3 of a themed week on the blog. I was feeling like I've been spinning my wheels here & am eager to try something new. Love to hear feedback or ideas.
