Chiropractic’s Basic Theory

Vertebral Subluxations are displacements of the spinal bones (vertebrae) that can cause endangering stress to your spinal cord and nervous system.

These subluxations are often due to poor sleeping habits, poor posture, strenuous exercise, injuries, auto accidents, sports, slips or falls, and the birthing process itself.

Chiropractic adjustments are very helpful in correcting these subluxations and restoring optimal health.

Homeopathy

• Law of similars: “Like cures like.”

• Effectiveness determined by “provings,” most of which were done 100 to 200 years ago.

• The greater the dilution, the more powerful the effect.

• Dilution may be below Avogadro’s number (1.063 x 1023).

Homeopathy Ultradilution

• 200C = 1 part in 100200

• 200C = At least one molecule of the original substance dissolved in a minimum of 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 molecules of water.

Multilevel Marketing (MLM)

• Most products have little or no appropriate use

• Those that do are overpriced• Vast majority of distributors make no

significant income• Professionals who can sell to a “captive

audience” can profit, but the process is unethical

• Enjoined by FTC• Banned from selling products other than publications

• Published best-seller

• Convicted felon

Kevin Trudeau says:• “There are natural cures for every disease.”• Our government and drug companies are conspiring to keep information from the public.

• “Drugs do not cure any disease.”• “Everyone is full of toxins and nutrient deficient.”

• “If you have no toxins nor deficiencies or electromagnetic chaos or stress, you cannot have any disease.”

• “Vaccines are loaded with poisons. Those who get vaccines are more likely to get sick than those who do not.”

• Have all amalgam fillings removed.

Weight Control Methods:FTC’s 7 “Red Flags”

• Cause weight loss of 2 pounds or more a week for a month or more without dieting or exercise

• Cause substantial weight loss no matter what or how much the consumer eats• Cause permanent weight loss (even when the consumer stops using product)• Block the absorption of fat or calories to enable consumers to lose substantial weight• Safely enable consumers to lose more than 3 pounds per week for more than 4

weeks• Cause substantial weight loss for all users• Cause substantial weight loss by wearing it on the body or rubbing it into the skin• A cancer was cured or put into remission by proven therapy, but questionable

therapy was also used and erroneously credited for the beneficial result • The cancer is progressing but is erroneously represented as slowed or cured. • The patient has died as a result of the cancer (or is lost to follow-up) but is

represented as cured. • The patient had a spontaneous remission (very rare) or slow-growing cancer that is

publicized as a cure.
