Yes, and no.
I use an over the counter diuretic instead of a prescription strength one, because the prescription strength ones are way too strong and I have had bad reactions. I retain water in my hands only, and if I don't take a diuretic then I can't use my hands some days. It's frustrating, but at least over the counter remedies do give me relief.
I take prescription allergy and acid reflux medicine though.
I'm not opposed to modern medicine at all, but on occasion I do find that the over the counter remedy, or the herbal remedy is better for my body (if only because they are not as strong in general, and I don't always need a battle axe to handle something that a hatchet could do).
