Wait... This tea is not going to do anything or maybe it will because of one ingredient. First, what concerns ulcer which is a sore in the stomach and upper part of the small intestine with keeping oral cavity health if we are talking about treatment and not prevention, if we want to keep our oral cavity, would use toothpaste. It mentions nourishing spleen and stomach and not treating the ulcer itself moreover not all peptic ulcers find their way to the spleen since the spleen only gets affected when the sore perforates through the stomach touching it which isn't often.

This is thought provoking; what am i seeing on the warm tips? Oh no, what concerns stomach or mouth ulcer with protect the kidney essence

How does oral or mouth ulcer reaches the mucus membrane of the mouth without causing injury to the outer part of the mouth first. The mucus membrane of the mouth would include the lamina propria, and the squamous epithelium or if I am wrong someone should help me out..

Only Licorice Root from the entire ingredient has to do with ulcer, and it isn't mouth ulcer it is gastric ulcer and it does this by increasing the mucus production. It bio-availability is low and researches are still being done to ascertain how it does this.

Her sister even testified to the effectiveness of the tea in relieving ulcer pains

This is possibly a placebo effect. A lot of people would experience a placebo effect because their immune system started fighting against something or working towards healing something and they give the credit to a placebo or the Licorice root doing its job.

These are the type of product that people like to buy and although I am a lady, we ladies tend to fall prey for anything tea and it started with slimy tea.
