Brown Residue/Tissue After Using Mouthwash: Identifying the Cause Ingredient
Question
When using mouthwash, brown residue or tissue comes out when rinsing. Based on the ingredient list provided, which ingredient in the mouthwash causes this phenomenon?
Answer
Hello!
The phenomenon of expelling brown residue or tissue after using mouthwash is often caused by certain ingredients reacting with proteins and mucus in your mouth.
From the list you provided, several plant extracts could potentially contribute to this, especially those rich in tannins or polyphenols.
The most common culprit for this specific effect is Tea Polyphenols (Camellia Sinensis Leaf Extract), also known as Green Tea Extract. Tannins in green tea can cause proteins in saliva and dead skin cells in the mouth to coagulate, forming visible particles or "tissue" that you then rinse out.
Other plant extracts like Ginseng, Licorice, Burdock, Bamboo, or Reishi Mushroom extracts might also have some astringent properties, but Green Tea Extract is the most likely cause among the ingredients listed.
This reaction is generally harmless and simply indicates that the ingredient is interacting with substances in your mouth.
