What is?

Food allergy?
Food allergy causes an immune response that can affect many organs in the body, causing numerous symptoms. In some cases the reaction to a food allergy can be extremely serious or even life-threatening. Nut allergies are a common example.

Food intolerance?
This can be characterised by your body lacking a chemical or enzyme needed to digest a certain food which can cause the same symptoms as an allergy. However, you may be able to eat small amounts of the food without causing a reaction. Lactose intolerance is a common example of food intolerance which is an absence of the enzyme lactase which is needed to fully digest a food.

Food sensitivity?
A sensitivity causes no immune response but your body can still react to the offending food item. Food sensitivities can often be eliminated by cutting the item out of your diet for 4 – 6 weeks. 

Symptoms Can Include

  •  Bloating and stomach cramps
  •     Constipation or diarrhoea
  •    Tiredness and fatigue
  •  Unexplained skin rashes
  •  Candida and yeast problems
  •  Headaches and migraines
  •  Runny Nose
  •  Reflux
  •  Skin Flushing

Why Test Hair?

When you are unwell it means the bodies energetic systems are out of balance. Hair can keep a longer lasting energetic record of what passes through the body than blood or urine, which are often tested.

Hair analysis is not a medical test. The test evaluates imbalances in you, evaluates and then re-balances your energetic systems: supplements, diet and homeopathic remedies are recommended to assist the body to start to heal, naturally.

Hair testing is very effective testing method

Obviously your doctor is the first port of call when dealing with your health however, when medical tests can prove inconclusive and treatment only palliates your condition than an energetic test may help. Our work is to identify any negative effects food or outside influences that may by having an affect on the body.
