Description

Technical Field

[0001] The invention relates to the technical field of medical and health care products, and in particular to a Chinese herbal medicine eye-improving health care patch containing a nitric oxide precursor and a preparation process thereof. Background Art

[0002] With the development of the information age, computers and mobile phones have become essential tools for everyone. People spend more than eight hours a day looking at their phones or computers. Therefore, the damage and overuse of computers and mobile phones to the eyes are self-evident. Eye fatigue has become the most common eye health problem today. Eye fatigue is also called visual fatigue. The main symptoms are dry eyes, astringent eyes, sore eyes, blurred vision and even decreased vision. Severe visual fatigue patients will also have varying degrees of systemic symptoms, such as headaches, dizziness, weakness, nausea and vomiting, which directly affect people's work and life. Therefore, relieving and treating eye fatigue is something that everyone should pay attention to. In order to relieve eye fatigue, in addition to natural rest and massage creams, various eye health products are also common ways. Among them, eye patches are one of the most widely used health care products for relieving and treating eye fatigue. They have many advantages such as easy use, low cost, multiple indications, and good effects.

[0003] At the same time, the latest research has found that vascular endothelial cells of the choroid and retina, outer segments of rod cells, retinal neurons, choroidal vascular nerve fibers, retinal pigment epithelial cells, etc., can all produce nitric oxide, and it is widely distributed in the tertiary neurons of the visual system. Further research has found that nitric oxide is not only a newly discovered neurotransmitter, but can also participate in visual development, integration and transmission of visual information with some neurotransmitters and neuropeptides, and participate in synaptic plasticity of the visual nervous system; moreover, nitric oxide can also dilate blood vessels, increase blood flow, and regulate the blood circulation of the central nervous system and the arteries and retinal capillaries inside and outside the eyeball, thereby improving symptoms such as eye fatigue and impaired vision caused by long-term use of the eyes by regulating blood circulation.

[0004] Therefore, the eye care patch is combined with a substance that can produce nitric oxide for relieving and treating eye fatigue, which has a positive effect on improving the relief and therapeutic effect of the eye care patch on eye fatigue. For example, patent CN107029037A is a kind of eye care patch based on the nitric oxide principle to improve the eyes, which is exactly according to the theory of traditional Chinese medicine and drug transdermal absorption technology, selects the drug formula, combines the traditional and modern technology to refine the eye care patch, can stimulate the eye peripheral nerve receptors and peripheral blood vessels, effectively improve the blood circulation around the eye and the internal nerve regulation, improve the blood circulation and metabolism of the eye tissue, restore the physiological regulation of the eye muscle, so as to achieve the purpose of effectively improving vision rehabilitation. However, the above-mentioned eye care patch is due to the problem of raw material selection and only adopting the traditional osmotic drug administration method, resulting in the poor effect of the health care patch, and the relief and therapeutic effect of the eye cannot reach the expected.
