Well, in Russia treatments to boost your immune system are a thing and they're used by people with herpes or hiv - before talking to Russians I had no idea they even existed. Some people report good results, others no change. It's not a final solution but it's not that expensive and it could be something western people would choose as well if it was an option. I can't say whether it's valuable or placebo effect but there is not much literature on the subject.

Some researchers in India came up with RISUG, a permanent but safely reversible male contraception. It's literally a piece of plastic, no hormones giving you cancer like female contraceptive, no life subscription to buy condoms and without the risks of a vasectomy. The treatment is so cheap that it never had financial backing and we're still stuck with subpart alternatives.

After being prescribed benzodiazepines I ignored the prescription because of how addictive they are and self medicated with cannabis. That's a substance which can be an alternative (in some cases), it's not addictive and doesn't give you withdrawal symptoms. And yet, it's still mostly illegal and getting a prescription is insanely hard, even when you qualify. Because of a condition I have, I qualify for medical cannabis in the country where I reside and I still haven't been able to get a valid prescription in 3+ years.
