Lemon Balm, chamomile, and Valerian root I've done as nerve tonics.<p>Echinacea/Goldenseal is my go to for a brewing sinus infection. Typically as a tincture in hot water. I do 3 droppers per big ads coffee cup worth of water, 3 times a day minimum once an infection is in full swing. If I catch it early, two droplets in some hot drink at least 3 times a day for a week or until symptoms stop usually does the trick.<p>I ended up resorting to it originally because every doc I went to refused to prescribe anti-biotics, and the infection had gotten to the point I could barely swallow, and a case of bronchitis and the asthma issued that come with it were about two or three days out.<p>Cinnamon is an okay anti-fungal in some cases. Usually use it on plants.<p>I can't tell you if it's all placebo effect or not, (except for the Echinacea/goldenseal) but the rest have all generally behaved as described in most herbal formularies as you find them in places like Tractor Supply. I've also got a copy of Gerard's Herbal (modern reprint of an old herbal guide from Elizabethan times I recall) for cross referencing with modern literature just to help with figuring out what is modern meme, what is unconfirmed academically, but was important enough to a several hundred odd year ago bloke to commit to paper and duplicate (effort to duplicate gives some level of credibility in my calculus), and what gets updated or preserved knowledgewise between back then and now.<p>I also experimented only with stuff I grew myself for the most part, and would only buy supplements after I'd determined the plant itself would do anything.<p>Plants, in short, are awesome. Not a substitute for a good doctor, but can go a damn sight further than a bad or no doctor.
