What is less well known, is that these antibiotics upset the balance of microflora and fauna in our intestines. The result of that is yeast infections. A rampant yeast overgrowth in the intestines releases toxins that mak a person feel tired all the time... and gas is produced so flatulence is a problem.
Someone I know was prescribed a common antibiotic for a toenail infection. After one dose, she began to feel bloated. I made an infusion with my store of Herbes de Provence and a few sprigs of rosemary. You can find Herbes de Provence on the spice rack in Cold Storage. It is normally used to season stews and meats in French cooking but I noted that it has proportions of rosemary, thyme and oregano (and others...) which all possess anti-bacterial &/or anti-fungal properties. I added fresh rosemary to the infusion to strengthen its anti-fungal properties.
I gave my friend a Yakult to drink, followed by this tea and within an hour, she felt much better. Instead of bloated, she was hungry. So I suppose the infusion was effective in killing the yeast overgrowth and the Yakult provided beneficial gut bacteria so that her intestines regained their microflora and fauna balance again.
