My annual GYN appointment for 14-years showed no change in my Fibroids. 13 Months of Dr. Smith’s Clinical Nutrition Therapy they were gone. Clinical Nutrition did in 13 months what medicine could not do in 14 years.

For 10 years I suffered with 40 bouts of Diarrhea every day. I saw many M.D.s, R.D.s, N.D.s, and Herbalists, locally, in Dallas, at the Mayo Clinic. I thought I had tried everything. Then my last physician referred me to Dr. Smith. Within one month, I had improved from 40 to 10 bouts daily; and at two months, I no longer had daily Diarrhea.

In the first six weeks on Dr. Smith’s Clinical Nutrition Therapy, my viral blood count dropped from 6.5 million to 2.5 million. If not for Dr. Smith’s Therapy, I would have died, instead of thriving as I am today.”

Before Dr. Smith’s Clinical Nutrition Skin Therapy, I had 11 Skin Conditions and the 11th was wrinkles. At 52, I looked like multiple tracks crossing in a railroad yard. In one month, 7 of the 11 conditions had improved. My Dermatologist said I was growing new healthy skin under the damaged skin.  He also said, 'In my 30 years of practice, I have never seen skin that had “no Impurities,” and even the best medical skin care products affect only ¼ skin depth compared to Dr. Smith’s Skin Therapy, which has tested to improve to the cell level of all skin layers. Dr. Smith, what is your Skin Care Secret?' "

(Skin Conditions) Melynda, 52 yrs., Wichita Falls, TX.

“For decades, I suffered with one bowel movement every two weeks (Ouch!), daily bouts of diarrhea and colon spasms.  My physician wanted me to have surgery, when I refused, he referred me to Dr. Smith.   Within 24 hours after starting Dr. Smith’s Clinical Nutrition Therapy, I began having daily bowel movements, after one week I had no more spasms and in one month, diarrhea was gone.  Dr. Smith’s findings from her Clinical Nutrition Analysis of my Blood Chemistry Lab Report indicated that it was my liver causing my colon symptoms, i.e., a type of chain reaction from the toxicity and dysfunction of the upper Gastro-Intestinal System having an adverse effect on my lower GI System. For decades, I had been receiving treatment for the wrong organ. All my colon symptoms were gone after detoxifying my liver and restoring Upper GI function.

(CONSTIPATION, IBS, SPASTIC COLON) Janet 29 yrs. Wichita Falls, TX.

“I had 25 symptoms, including hormone imbalance, anxiety, depression, lack of concentration, low sex drive, low immunity, fatigue and over-all body pain.

(hormone imbalance, anxiety & depression) Denise, 36 yrs., Howell, MI.

“For almost a year now, without any warning, my heart would beat so fast that my entire body shook, like I was having a seizure, except I would flop around like a fish and it was my heart, not my brain causing it.  As I was getting worse, I would have several episodes daily.  Though I saw several heart specialists, no one knew how to help me until my father referred me to Dr. Smith.  Within the first week, I stopped having daily episodes and within a month, my heart functioned normally.”

(RAPID HEART BEATS) Micki, 19 yrs., Nocona, TX.

    Since 1981, Dr. Smith’s New Client Survey has proven that even with all of the published dietary, nutritional supplement and lifestyle information online and in books, the public still only knows less than 30% of the information in Dr. Smith’s Personal Education Program (PEP).

    This means that the other 70% they need to know to develop a principle-centered healthy diet and lifestyle is unknown and unavailable to them, except through informed nutritional health care professionals, like Dr. Smith. This is the #1 reason why people are still searching.

The First Step In My Journey From There To Here!

When I was 24, one of my roommates lent me a book on "Herbs."   I was not aware at the time that herbs and whole foods were God's medicines.   The first Herb from the book that got my attention was Yarrow, when I read Yarrow Flower Tops makes a hair rinse for blondes.   A few months after switching my commerical hair rinse to  Yarrow, the recipe below became a favorite request from the blondes in my church.  

Yarrow Hair Rinse Recipe
