I use Energetix formulas , these are a mixture of herbal tinctures and homeopathic Nosodes.

The ones I have used that have been invaluable are

Core Artemsia - for parasites
Para-chord- Homeopathic te-toxifier for Parasites
Liver tone- Liver support.
Kidney tone - kidney cleansing and support
Lymph Tone- homeopathic for drainage and detox

I have ben taking them for a couple of years now and believe they are extremely effective.

They are readily available in the USA. just search on the web. some companies require they are adminstered by a ND other supplies do not ask.
I am in the UK and was originally supplied them by my ND who is both a trained Naturapath and Homeopath.
