Questions on Humaworm cleansing

RG,
I would like to know, when you have never really cleansed and you are 40 or even younger maybe, does it take several years of cleansing to kill all the parasites, viruses, bacteria, ect. from your body? If so, how many years or does it depend on the individual and what they have in them?
Also do you need to do a liver flush in order to really get your liver working properly or will it do this on it's own after you get straighten out?
I value your knowledge and expertise.
Thank you,
Shelly
