Hey thanks for the replies. Alcohol tinctures here too. I tried buhners energy formula, it sort of worked but my digestion seemed to stop working, I wasn't going to the loo for like 2 days! Was rather worrying so had to stop. Second symptom felt like low blood sugar (but wasn't as I tried the fixes for hypoglycemia) I now think the powders were lowering my blood pressure, but it was lasted well over 6 hours. Not what you want.
The issue really with a lot of these herbs is that they aren't particularly potent. There are almost no in vivo studies for the likes or oregano etc as well and even following symptoms after taking something (herx's are quite hard to really follow and could be due to anything). This makes it difficult to know what is and what is not potent.
Branding and manufacturing process is another issue. Take Andrographis Paniculata for example, I've tried dozens of manufactured versions of this herb, from india and from herbalists in Scotland. The only one that appears to have any benefit for ME is Pukka branded Andrographis Paniculata. Over about a year + I went from only being able to tolerate one capsule (severe flu like symptoms or close to it after taking it) to being able to take 15g a day (which is about one bottle) in cases of acute viral infection. This herb is amazing as well, it crosses the blood brain barrier and has a variety of soothing effects, neuroprotective, benzo type effects on the brain, etc. Sadly most herbal complexes or treatments I've got on well with make me extremely hungry and then give me anxiety, almost everything does this. Hence why I take them sparingly.
I'm sure some herbal compounds are potent enough, it's just figuring out which ones. But Lauricidin and Andrographis Paniculata are great parasite/bacteria killers for sure. I often feel better after a course of Andro for about 3 to 4 weeks before the effects start to wear off.
