Back when Japan was still in a period of civil war, People made tea from this tree and used it to heal eye injuries. (wash the eyes with cooled tea ) According to legend, it improves your eyesight, allowing you to see up to 400 km away. This story takes place over 600 years ago.
I suffered from "dry eyes", so I drink it once every three days. It's more effective than the medication prescribed by doctors, but you need to continue drinking that tea.
For eye injuries, It worked well when my dog injured his eye. I used it by dropping it in like eye drops (Of course, the doctor prescribed three types of eye drops for a week, but it didn't heal well. The tea helped it heal faster.)
The tea is made from dried and crushed branches and leaves, and you boil 10g of them in about 1,5 liter of water for about 10 minutes. The taste is extremely bitter.
I have planted one tree in my garden, but it doesn't grow big right away. Then, I buy the tea leaf.
The leaves are characterized by being made up of three leaflets joined together, and they turn salmon pink in the autumn.
The name of the tree is "Megusuri no ki ", English name is Nikko maple ? (Acer maximowiczianum)
It is also effective for severe burns inside the mouth. However, for pain caused by a virus, this herb Strawberry Geranium is recommended.
If blindness is a concern, you should see an ophthalmologist immediately, but for preventative measures of Glaucoma and cataracts, I recommend learning and pressing acupressure points as well as this tea.
