Complate Body cleansing in Mikhail Tombak's book
I came across Hulda's Clark books were she talked about importance of body cleansing. I used
Liver Cleansing technique from her book. Later I did even more extreme body cleansing by Richard Anderson (Cleanse & Purify Thyself). I noticed definite improvement in my stomach problems.
Then my friend recommended Can We Live 150 Years by Tombak. It really helped me see the "big picture" and "put the pieces together". The author explores factors leading to sickness and premature aging, and then proceeds to preventative techniques. He also talks about importance of simple spine exercises, simple breathing techniques, proper food combination and the importance of one's attitude towards life.
The most important for me were his simple techniques for the whole body cleansing (extremely effective for me!), starting from large intestine, liver cleansing, bone and joint cleansing, kidney and blood cleansing, circulatory system cleansing.
