Ayurveda, an ancient Indian medical system maintains that although allergens such as pollen, dust, and dander trigger symptoms in susceptible people, they are not the primary cause of allergies instead it is the accumulation of ama (toxic) and low immunity.
Ayurveda emphasis that the improperly digested foods (ama), and impurities, such as chemical additives, are absorbed into the body, travel through the circulation and lodge in the respiratory tissues, skin and other tissues prone to allergy.
These accumulated wastes and toxins block the channels, trapping the toxins inside the tissues, and activating the immune system.

• When this toxics material interact with the Skin, they can cause rashes, itching,burning sensations and discoloration.
  
• If the respiratory tract is involved, sneezing, inflammation and mucous drainage will occur.
  
• If the tissue involved is the digestive tract, diarrhea can result.
  

The qualities that predominate and the season or conditions that bring on or worsen the allergy reveal the doshas that are involved.
Determining the dominant aggravated dosha helps in the creation of an individual-specific treatment plan.

• Vata type allergies may present with symptoms of dry cough with dry phlegm, headaches, anxiety, insomnia, and irregular digestion and elimination, and will likely worsen in dry or windy environments and in the fall season.
  
• Pitta type allergies will show up as heated symptoms such as burning eyes, rashes, loose stool, and irritation and may get worse in hot environments and the summer time.
  
• Kapha, being moist, dull, and heavy, will have the most abundant clear or cloudy mucous production and sluggish digestion, and will worsen in the spring time as the weather warms up and the accumulated kapha from the winter begins to "melt.
  "

From an Ayurvedic perspective, allergies, as with any condition, reflect a unique situation in each person's array of symptoms and underlying imbalances and its allergy treatment will emphasize on the four steps: boost the digestive fire, adjust the diet to support a "clean burn," detoxify, and restore the strength of the immune system.
