Almost a third of the world's population suffers from allergies. Allergies are predicted to become even more prevalent within this decade and could affect half of the population. 
Very different factors can provoke the development of allergies. The two main prerequisites are:
- weakened immunity;
- problems with the gastrointestinal tract: imbalance of microflora, parasites.
There is also evidence that allergies are associated with an urban lifestyle, that is, an unfavorable environment. 
Three features of cedar nut oil make it an effective remedy against any allergy: the oil strengthens the immune system, supports the health of the gastrointestinal tract, and has a detoxifying effect.
A weakened immune system can trigger the development of an allergy to any external irritant, especially a food allergy.  Cedar nut oil is a source of nutrients necessary for the formation and maintenance of immunity:
- minerals: selenium, zinc, copper, and magnesium;
- vitamins A and E;
- the amino acids glutamine, arginine, and lysine.
Boosting immunity also has an indirect effect on reducing the risk of allergies. Transferred infectious diseases can become a trigger for the development of allergic reactions. A stronger immune system helps the body resist infections and therefore eliminates an additional risk factor.
Problems with the gastrointestinal tract are directly related to immunity disorders, and, as a result, an imbalance in the microflora often leads to the development of allergies. Cedar nut oil contributes to the formation of healthy microflora in the intestine due to the fact that it:
- contains prebiotic substances: polysaccharides, fatty acids, antioxidant vitamins, and amino acids valine, arginine. These substances are fermented by beneficial microflora and thus stimulate its growth.
- contains nutrients that maintain the integrity and health of the mucosa, thereby preventing the reproduction of pathogenic microflora.
The cause of up to 50-80% of all allergies is infection of the body with parasites. In addition, as mentioned above, the development of allergies may be associated with poisoning with toxins due to unfavorable environmental conditions. Cedar nut oil has a detoxifying effect due to the large amount of amino acids in its composition. Amino acids "bind" pathogens and toxins, which facilitates their further removal from the body. Some of the amino acids in the composition of cedar nut oil (for example, cysteine) contribute to the removal of even heavy metals from the body and reduce the negative effect of radiation exposure.
So, cedar nut oil has a complex positive effect on health, which reduces the risk of developing allergies and reduces its negative manifestations.
