List of Conditions and Symptons Relieved &
Diseases Cured by
Vitamin C


Excerpted from:

The Clinical Experiences of Frederick R. Klenner, M.D., abbreviated, summarized and annotated by Lendon H. Smith, M.D., 2233 SW Market Street, Portland, Oregon 97201

His maxim: “the patient should get large doses of Vitamin C in all pathological conditions while the physician ponders the diagnosis.”

  • Acute and Chronic Pancreatitis
  • Arthritis


    • Dr. Klenner is convinced that C will work in any problem but the negative results reported are only because an insufficient amount was used.

  • Barbiturate poisoning

  • Burns


    • “Massive use of C is compatible with any other drug and in most instances it will enhance the value of these other remedies.”

  • Cardiovascular diseases
  • Cavities
  • Chicken pox
  • Chronic cystitis
  • Corneal ulcers
  • Carbon Monoxide Poisoning


    • This has been Dr. Klenner’s main complaint: failure to benefit from Vitamin C use is usually due to inadequate amounts being used for too short a period of time.

  • Diabetes
  • Diphtheria
  • Disc, ruptured intervertebral


    • If enough Vitamin C is supplied, the enzyme system that breaks down invading viruses and bacteria will be able to do its job properly. Quote: “Unless the white blood cells are saturated with ascorbic acid, they are like soldiers without bullets.”

  • Glaucoma

  • Flu – all flu and viral infections

  • Heat Stroke
  • Heavy Metal Poisonings (Lead & Mercury)
  • Hyper menorrhea
  • Herpes Simplex & Zoster
  • Hypoascorbemia (insufficient Vitamin C)


    • He got to know the vulnerability of viruses so well, he played games with them. “When proper amounts are used it will destroy all virus organisms.”

  • Insidious Virus (Flu and other viral and viral related illnesses)
  • Insect Bites (Black Widow spider, others)


    • “If the activity of the pathogen is completely stopped, the development of active immunity will be interrupted.”

  • Measles
  • Mononucleosis
  • Multiple sclerosis
  • Mumps
  • Myelocytic Leukemia


    • As these cases show Dr. Klenner was confident that the C would handle the virus, but he needed the antibiotics to control the bacterial secondary invaders.

  • Peptic and duodenal ulcers
  • Pesticide poisoning
  • Post operative and radiation sickness
  • Polio
  • Pregnancy (Very healthy babies)


    • He summarized the function of C in poliomyelitis:

  • 1. Virus destruction.
  • 2. Dehydrates the brain and the spinal cord safely.
  • 3. Supports and normalized the stressed adrenal glands.
  • 4. It preserves the lining of the central canal and maintains more regular spacing and less crowding of ependymal cells (surface cells of the spinal cord).


  • Radiation side effects
  • Rheumatic fever
  • Rocky Mountain Spotted Fever


    • “Even when there is not a single outward symptom of trouble, a person may be in a state of Vitamin C deficiency more dangerous than scurvy itself. When such a condition is not detected, and continues uncorrected, the teeth and bones will be damaged, and what may be even more serious, the blood stream is weakened to the point where it can no longer resist or fight infections not so easily cured as scurvy.

  • Scarlet fever
  • Schizophrenia
  • Snake bite
  • Sunburn


    • He also felt—as do Archie Kalikarinos and Glen Dettman of Australia—that the dreaded Sudden Infant Death Syndrome was basically a Vitamin C deficiency.

  • TB (Tuberculosis)
  • Tetanus (Lockjaw)
  • Toxins (neutralizes & flushes)


    • His maxim: the patient should “get large doses of Vitamin C in all pathological conditions while the physician ponders the diagnosis.”

  • Trichinosis


    • “It appears that Vitamin C acts as a reducing agent, an oxidizing agent, an anti-clotting agent, an antihistamine, and as an anti-infective agent.”

  • Urethritis


    • As these cases show Dr. Klenner was confident that the C would handle the virus, but he needed the antibiotics to control the bacterial secondary invaders.

  • Viral hepatitis (infectious and serum)
  • Viral pneumonia


    • How does Vitamin C work: as an oxidizing agent massive amounts, i.e., 5-150 grams, intravenously, for certain pathological conditions, if allowed to run in rapidly (20 gauge needle), acts as a “Flash Oxidizer” and may correct the condition in minutes. It can be a reducing agent. It neutralized toxins, viruses and histamine. The more serious the condition, the more C is required.
