I use a lot of Manuka honey: internally and externally... It's a good antiseptic too... Great for wound healing. Expensive but that's usually the way isn't it? That's why cheap things with petrochemicals are so embraced I guess. I find though that if you get back to basics ( by avoiding too much processed foods) that good health follows which is the cheapest outcome of all. Yes good old lemon, garlic and honey are the safest.... And drinking lots of water... Us humans tend to have faith in the more complex solution when in reality keeping it simple is best.
