yes the price is high.
but I feel the book is worth it.
the testing procedures are very accurate. I go to a doctor that does CRA and she has found that its so acurate that she no longer needs to do lab tests.
now that i think the book wouldnt be so great for 'laypeople' as it does assume some knowledge of anatomy/phyiology and acupuncture meridians. the tests also are very organ/gland specific. unless you have a good working knoeledge of herbs and homeopathy you might find your self stumped as what to do with the test results.
I have a few touch for health books and have been to a couple TFH classes. they are fun. but very general. I wouldnt recomend TFH unless you are already an acupuncturist or a massage therapist. its not that its difficult to learn, I just felt it was kind of useless on its own.
