Hi fellow Brit!
I started on a tincture December of last year. Similar but slightly different, it was an Energetix tincture containing Black green walnut, wormword, cloves etc. it was prescirbed by my UK Naturapath so I had her support and she had a lot of experience on its use.
I took 30 drops twice a day. This is about one dropper full morning and evening. Do take it in a glass of water, it tastes rather like creosote [due to the oil of cloves....] so perhaps have some fruit juice ready to kill the taste.
I started to get a reaction/die off symptoms after about 9 days. I had a very strange sore throat that was at the back of my nose that lasted three weeks, I got blocked ears/ear ache etc. This was probably because the parasites were carrying strep/Staph pathogens that passed to me when the parasites started dying. I also got a very large, loose bowel movement at about the same period of time as the intestinal parasites passed out.
Drink alot of water when you are on the treatment and take lots of milk thistle etc to support the liver whilst your body is going thru this very tough detox process!
