Improper use of apple cider vinegar presents serious health risks that are frequently neglected. Ingestion of the product in undiluted form produces irreparable damage to the enamel of the teeth. The direct application of the liquid to the skin produces harmful chemical burns and irritations. The digestive mechanism suffers as a result of the effects of acid reflux. The medication interactions with use can be serious with blood thinners or diabetes medication.

Oral Health Damage

  • Acetic acid erodes tooth enamel within 30 seconds of contact
  • Increased cavity risk from prolonged enamel exposure
  • Tooth sensitivity develops with repeated undiluted use

Skin Injuries

  • Chemical burns occur at concentrations above 5% acidity
  • Permanent hyperpigmentation from repeated inflammation
  • Worsened acne and eczema symptoms from pH disruption

Digestive problems arise rather quickly among those who improperly use vinegar. Those suffering from acid reflux have their troubles increased by the consumption of vinegar. Ulcers are particularly prone to bleeding due to the increased acidity. Those persons who have sensitive digestion experience cramping and nausea. These effects are evident even in small doses and in individuals who are already constitutionally predisposed to them.

Prevention is based on strict dilutions. Always mix one tablespoon of vinegar in eight ounces of water for drinking. One part vinegar, four parts water for skin application. Always take no more than two tablespoons daily. This reduces but does not eliminate risks.

Special precautions are necessary for high-risk groups: Those who have kidney conditions are in danger of dangerous electrolyte imbalances. Treatment should be avoided entirely by pregnant women. Those using multiple medications should have the treatment prescribed by their physician. Children under 12 shouldn't take vinegar in any form.

Recognize early warning signs immediately. Tooth sensitivity indicates that enamel recession has begun. Skin redness suggests the development of chemical burns. Digestive pains indicate an excessively high level of acidity exists. Cease use immediately on appearance. Seek medical attention if symptoms continue beyond twenty-four hours.
