Among various actions of Physostigma, if we have to pick the most prominent one then that would be on the eyes. It acts magnificently on the eyes and deals effectively with numerous eye-related problems. To begin with, it is a highly beneficial medicine for cases of myopia. Myopia, also known as near sightedness and short-sightedness, is a vision condition in which the sufferer can see near objects clearly but farther objects are blurry. It can be of great help in cases where myopia is increasing. Secondly, it is a well-indicated medicine for cases of glaucoma (a condition that causes damage to the eye’s optic nerve). It is prominently indicated for glaucoma that follows after an eye injury. It is useful to manage cases of muscae volitantes (eye floaters). Here its use is primarily considered when there occur black spots or flashes of light before eyes.
