The history of Kumokiri-Megusuri

My family followed from generation to generation all the time as “Eye Drops Store” for several hundred years since 1543.

In ancestor, Jubei Kasahara produced “Zenko-ji Kumokiri-Megusuri” in ancient times of Tenbun-Era (1543). It was the thing that Eye-Drops paste of the form of ointment was put in a shellfish and was used as it is or dissolved it in water to use it. We received many good reviews from customers “Stinging but it works well” , and also it has been valued highly and used for other purpose expect as Eye-Drops when there was not enough medicine.

After many years, call had been growing louder for the revival of “Kumokiri-Megusuri” from all of the places. After selling it in form of the current Eye-Drops, it was pleased by many people.

Berberine of the Phellodendron Bark inside which is a chief ingredient of “Kumokiri-Hyakusogan” and Glycyrrhizin of the Licorice inside are combined with this Eye-Drops and show an effect to an eyestrain, itchy eye, hyperemia and bleariness.
