Medicinal uses

Some of the most common medicinal uses of garlic are

  • Fungal infections treatment. Both internally and externally manifested fungal infections do not develop resistance to garlic unlike the case with anti-fungal medications. Most frequently garlic saturated oils and garlic extracts are used for infections such as ringworm, athlete’s foot, jock itch, intestinal and vaginal Candida overgrowth. Garlic also has a slight antibacterial effect on H.Pylori infection and can be used as an addition to other anti H. Pylori agents, including antibiotics.
  • Cancers. Daily garlic consumption can be beneficial in helping to prevent various cancers, such as cancers of colon, rectal, stomach, breasts and lungs.
  • High blood pressure, high cholesterol and hardening of the arteries are helped by a regular consumption of garlic.

Too much garlic consumption can be dangerous to health

While reasonable consumption of garlic on a daily basis is claimed to be beneficial, excessive use of garlic internally can produce negative impacts on health.

Garlic is considered to be toxic. This is mostly due to its sulphone hydroxyl ion component of garlic, which is capable of penetrating the blood-brain barrier, and is toxic to brain cells. Garlic is also highly toxic to dogs and cats and can fatally poison animals. In Ayurvedic medicine, the oldest form of medicine, garlic is not recommended for any substantial treatments.

Some of the adverse effects of garlic consumption are

  • Blood toxicity. Even small amounts of garlic substance in the blood stream are highly toxic to humans. If you are affected by a low stomach acid condition (GERD is one of them) and your digestive track is not in optimal health and there is a presence of leaky gut condition, garlic can be very poisonous to you. With leaky gut (Bowel hyper permeability), garlic substances can easily get into the blood stream and cause symptoms of toxicity such as
    • Irregular heart beat
    • Anxiety
    • Insomnia
    • Skin rashes
    • Arterial fibrillations
    • Headaches
    • Neurological disorders
  • In its raw state, garlic can promote botulism when soaked in oils. Garlic contains a neurotoxin that can cause paralysis of the muscles.
  • Stomach lining irritation is one of the most frequent side effects of moderate garlic consumption.
  • Blood thinning effect is substantial when moderate amounts of garlic are used on a daily basis. It can promote poor wound healing and cause extensive bleeding during a surgery. Garlic supplements and garlic rich foods have to be stopped at least two weeks prior to any surgery. Garlic also interferes with anti-coagulant medications used in surgery.
  • Inhalation of garlic vapors can trigger an asthma attack.
  • Allicin, the compound from a raw crushed garlic can be very irritating to someone with sensitive skin. When skin is exposed too much garlic, it can become red, irritated and sore.

As with any substances, garlic can be beneficial and toxic at the same time. Consult with your medical care provider before taking any garlic supplements that may exceed a reasonable dietary garlic consumption.
