The Thyroid Gland: Part of our Delicate Endocrine System and Its Relationship to Total Body Function

“The Distinguished Specialist will be one who regards His field of study in its Intimate Relationships to the Body as a Whole.”  Francis Marion Pottenger M.D. 1923

Thyroid Gland

  • Located at the base of the neck
  • Shaped like a butterfly
  • Part of the Endocrine System (Endocrine Gland-A gland that produces and secretes hormones)
  • Nerve Innervation from the 5th Cervical nerve through the 1st Thoracic nerve
  • Nerve supply from the Cervical Sympathetic Ganglia of the Autonomic Nervous System
  • Parasympathetic nerve fibers from the Vagus Nerve
  • Extensive Lymphatic Drainage that flow Multidirectional

Function of the Thyroid Gland

Production of Thyroid Hormones, T3 and T4

  • T4 (Thyroxine): Inactive .7-2.0 ng
  • T3 (Triidothyroxine): Active but used 25%-35% 1/3 of sites filled (0.80-1.20%)

TBH Thyroid Binding

Hormones: Binds Estrogen (holds T4 in the blood) 1.2-2.5 mg (men) 1.4-3.0 mg/dl (women)

  • Keeps vital organs warm i.e Heart
  • Stores Iodine: The most essential requirement to make ALL thyroid hormones
  • Instrumental in our Basal Metabolic Function, BMR
  • Communicates with all the Endocrine Glands
  • Repsonds to TSH, produced by the Anterior Pituitary Gland 0.35*5.5 mclIU/ml Opt 1.0-2.5mclIU/ml
  • Decreased=Hyperthyroid
  • Increased=Hypothyroid

Signs and Symptoms of Thyroid Dysfunction

  • Fatigued
  • Depressed
  • Cold Extremities/Intolerance to cold
  • Constant headaches
  • Slow recovery from injuries
  • Unexplained weight gain
  • Poor memory
  • Loss of eyebrows from the sides
  • Loss of hair, eyelashes, etc
  • Hoarse voice
  • Difficulty in swallowing
  • Slowed speech
  • Puffy face
  • Drooping eyelids
  • Constipation
  • Dry, scaly, thick coarse hair
  • Raised, thickened skin over the shins
  • Carpal Tunnel syndrome
  • Confusion
  • In children, growth retardation, delayed teething and mental deficiency
  • Dementia
  • Menstrual cramps or other menstrual disorders
  • Fribrosystic Breast Condition
  • Prostate Issues
  • Dry, brittle nails
  • PCOD

Physical Signs and Diagnosis for low Thyroid/Hypothyroidism

  • Low body temperature
  • Anemia (Iron deficient)
  • Reflexes-brisk contraction and slow relaxation times
  • Enlarged heart-loss of peripheral circulation
  • Palms and soles slightly orange hue
  • Goiter

Lab Tests

  • Blood tests show decreased thyroid hormones
  • T4
  • T3
  • Presence of auto-antibodies
  • Increased TSH
  • High cholesterol

Signs for Hyperthyroidism (Overactive Metabolic State Graves Disease)

  • Racing or irregular heart rate
  • Extreme, quick weight loss
  • Tremors
  • Anxiety
  • Goiter

Lab Tests

  • Low TSH
  • High T3
  • High T4


  • WHO claims that Iodine deficiency is the world’s greatest single cause of preventable retardation
  • Iodine is the largest element that we use in the body
  • It is the ESSENTIAL requirement to make Thyroid hormones


  • Discovered in 1811
  • Birth of Western Medicine 1811
  • 1824 Boussiqualt observed no goiters at silver mines where iodine was plentiful
  • 1829 Dr. Jean Lugol, a French physician found that Potassium Iodide added to water increased solubility of iodine.  Thus “Lugol’s” Solution” was born!
  • Lugol’s Solution = 5% Iodine and 10% Potassium Iodide and 85% distilled water.
  • Two drops= 12.5 mg KI, very similar to the physiological makeup of Iodine sufficiency of our entire body (ideally)
  • First single element to treat any disease (goiter)
  • RDA recommends only 150 mcg, just enough to prevent goiters (the US started iodizing salt in 1920, which was advised to the rest of the world in 1831


  • *Fluorine-Most reactive
  • *Chlorine
  • *Bromine
  • Iodine-least reactive
  • *Goitergens
  • *NIS (Sodium-Iodide Symporter) Enzyme system to concentrate iodide
  • *General enzyme inhibitor

Enzymes = life!

Inhibitors = anti-life

Displacement Chemistry: Most reactive halide will displace least reactive halide.  Therefore, they can all replace iodine/iodide!

NIS (Sodium Import System) Located in :

  • Mammary Gland
  • Choroid Plexus
  • Ciliary Body
  • Skin
  • Placenta
  • Etc


  • Thyroid Gland – Highest concentration
  • Breasts – Highest volume

Dr Jarvis stated that the blood passes thru the Thyroid gland every 17 minutes to “pick up” iodine and transport it through the body  if there is insufficient iodine, then it picks up the halogens that are closely related to iodine i.e. fluoride.

Iodine & Its Important Role in Our Health

  • Makes T3 and T4
  • Rids body of abnormal cells, including cancer cells
  • Detoxifies chemicals directly
  • Antiseptic to bacteria, fungi, viruses and protozoa
  • Detoxifies toxins, food poisoning snake venoms, etc
  • Prevents Fibrocystic Breast Disease
  • Protects against breast cancer
  • Antiseptic activity in stomach against helicobacter pylori
  • Decreases risk of CAD-protects double bond in lipids…Important for CVS and synaptic membranes in brain and retina
