Simple but powerful. You can buy ready made tea that has a detoxifying effect and I do have that as well. Although the herb of my choice this week has been sage.
You cook 1 & 1/2 tbsp of sage leaves in 1/2 l water for three minutes. Put it into a flask and drink it over the day. 1/2l is not much for a day so a sip here and there does the job. Sage is has among many others, antimicrobial properties.
The taste gets quiet strong. I happen to love sage so no problem;)
