1. What is an allergic reaction?

An allergy symptom is the overreaction of our immune system to some harmless substances.
The normally harmless substances, we call them allergens, create IgE antibodies and connect to our mast cell that carries histamines.
Once allergens tough the IgE antibodies, they send signals to the mast cell to release histamines.

2. How EGCG3″Me catechin works?

4. Brewing Guide – How to maximize the benefits of MCGC3″Me for your allergy

4-1. Green tea, not oolong tea or black tea

Many cultivars rich in EGCG3″Me were developed for Japanese black tea.  It tastes great for black tea but EGCG3″Me is disappeared by the making process of black tea.  So please choose green tea if you want to take EGCG3″Me.  This catechin has a strong bitter and astringent taste. 

4-2. Start drinking before allergy season

If your allergy is seasonal, we recommend starting to drink before the allergy season.  It works better than start drinking after you develop the symptoms.   If you have a year-round allergy, start any time!  

4-3. Use hot water and stir well

EGCG3″Me is extracted well to hot water.  Please stir well if you use powder tea.  If you use leaf tea or teabag, steep for 5 min.  And make your tea only for your immediate consumption

4-4. Don’t brew with cold water

Don’t leave tea for a long time after you brew.  Because there are some chances your tea will make pheophorbide that can cause photosensitive dermatitis.  Brewing with lukewarm water(40C / 104F) is not recommended either.
