Euphrasia (2017) Alone and in Combination with other Homeopathics

Euphrasia

2014

This in-vitro (in the lab) study investigated the effects of Euphrasia officinalis (eyebright) with respect to protecting human corneal epithelial cells.

They tested the protective effects against several types of toxins and using several types of preparations of the herbs. Three types of extract solvents were tested: one using heptane, one using ethanol, and one using ethyl acetate.

The extracts formulated using heptane were toxic to the cells and did not reduce free radicals. All of the extracts did decrease several kinds of inflammation in the corneal cells.

They concluded that the preparation using either ethanol or ethyl acetate extracts would be suitable for eye therapy preparations.

Euphrasia & Chamomilla

2017

Researchers wanted to investigate the efficacy of a commercial eye drop that contains several homeopathic remedies traditionally known to be helpful for vision. In addition, they wanted to gain an understanding of the mechanics of such protection.

The eyedrop contains Chamomilla matricaria and Euphrasia officinalis (eyebright). It was tested extracted human cells from the cornea which were exposed to UVB radiation. Such exposure causes oxidative stress to the eyes as well as inflammation of the cornea.

Antioxidants protect against oxidative stress. The scientists measured the potential antioxidant action and total content of the beneficial bio-chemicals known as phenols. They also evaluated health of the cells exposed to UVB radiation, wound healing, free radical levels, oxidative damage and expression of specific genes.

They found that the drops were able to protect the corneal epithelial cells from cell death due to UVB radiation and helped wounds heal. They also found that antioxidant levels increased and inflammation decreased.
