According to the information, the eye drop formula, besides foxtail grass, also included Pearl Powder, Shi Jueming, and natural Camphor.
Pearl Powder is made by grinding solid particles from the shells or pearl sacs of pearl-producing mollusks. In Traditional Chinese Medicine, it is considered "cold" in nature, has a sweet and salty taste, and targets the Heart and Liver meridians. It is widely used for its many clinical effects, including calming the spirit, easing tremors, brightening the eyes, clearing away corneal opacity, detoxifying the body, and promoting tissue regeneration.
Shi Jueming consists of the shells from various abalone species, such as the variegated abalone, wrinkled-disk abalone, sheep's ear abalone, Australian abalone, ear-shell abalone, or white abalone.
Its primary function is to clear the Liver and improve vision.
Natural Camphor is not what most people think of as ice.
