Ginger extract has many benefits for women. It can improve visual fatigue and shoulder stiffness.

With the increasing use and popularity of electronic products, the faster pace of life and work, and the increasing number of people engaged in text and other close-range eye work, visual fatigue has gradually become the most common disease in ophthalmology. Visual fatigue can include organic factors of the eyes and the whole body as well as mental and psychological factors. The three interact with each other. Clinically, it can be manifested as a syndrome of visual impairment, eye discomfort, dry eyes, itchy eyes, swelling and pain, dizziness and systemic symptoms after using the eyes, and even the inability to perform normal visual work, which is also called eye fatigue syndrome. Visual fatigue is the main factor that induces myopia and causes myopia to deepen. Epidemiological surveys show that 18% of children and 90% of digital device users will experience varying degrees of visual fatigue. Another common problem of desk workers is shoulder and neck stiffness, which seems to be an old problem that modern people are inseparable from. Most people have poor posture. Shoulder stiffness belongs to what is medically called "myofascial pain syndrome". Usually there are several places in the shoulder and neck area that feel painful after pressing with fingers. Maintaining the same posture for a long time can easily lead to poor blood circulation, muscle fatigue, hypoxia, and inflammation and soreness of the fascia. 

A recent Japanese clinical study on 100 healthy adults aged 20-73 showed that taking ginger extract capsules daily for eight weeks, eye blood flow, peripheral blood flow, eye fatigue (visual analog scale [VAS]), shoulder stiffness (VAS), body warmth (VAS) and shoulder muscle stiffness were evaluated at week 0, week 4 and week 8. Group analysis by age (≥51 years or less) showed that ginger's promotion of peripheral blood flow in deep blood vessels was limited to women under 51 years old. Similarly, subjective complaints such as eye fatigue and shoulder stiffness in women under 51 years old were also improved by eating ginger. After eating ginger, the body temperature of men aged ≥51 years changed significantly. There was no statistically significant change in muscle stiffness. In conclusion, ginger consumption can reduce eye fatigue and shoulder stiffness by enhancing peripheral blood flow in relatively young women.

Ginger is used as a medicinal herb worldwide. The main active ingredients of ginger are gingerols, and zingerone, which are pungent compounds. These ingredients have anti-inflammatory and antioxidant activities, which have been demonstrated in vitro and in vivo in animal models and in cancer patients. Some studies have shown that ginger consumption can reduce nausea and vomiting during pregnancy, improve metabolic syndrome and pain. Ginger is also a major ingredient in Chinese condiments and is believed to have a variety of health benefits, such as improving fever function and accelerating blood flow. The effect of ginger on blood flow in young women may be due to its effect on estrogen. It has been reported that oral administration of ginger extract can induce an increase in estrogen and glutathione in mice under stress conditions. Studies have also shown that estrogen reduces cerebral vascular tone and increases cerebral blood flow by promoting endothelial-derived NO and prostacyclin pathways, while testosterone has the opposite effect. In addition, estrogen can enhance NO production, promote vasodilation, and increase blood flow. The increase in blood flow in young women may be due to vasodilation caused by increased estrogen levels after eating ginger. The increase in blood flow velocity caused by eating  ginger is mainly in the deep blood vessels, not the superficial ones. This may be because the superficial blood vessels are easily affected by the environment, while the deep blood vessels can more accurately reflect the effect of ginger.

The incidence of myopia in middle-aged Asians is relatively high, and myopia is more serious in preschoolers and school students. Myopia is a known risk factor for glaucoma. In this study, it was shown that after 8 weeks of intervention, the axial length of the ginger group decreased by 0.006 mm. From a clinical point of view, this seems insignificant, but if it continues to shorten, it will decrease by 0.038 mm per year. It can be seen that ginger is beneficial for myopia. At present, for different causes of visual fatigue syndrome, the existing treatment methods include: ① Correction of refractive error. The treatment of visual fatigue takes correction of refractive error as the first measure, wearing appropriate glasses, and cooperating with extraocular muscle training to improve binocular coordination. ② Surgical method. Medial rectus muscle resection, lateral rectus muscle retardation. ③ Extraocular muscle training. ④ Chemical drug treatment. For patients who may have parasympathetic nerve excitation and abnormal regulation, the topical use of low-dose cyclopentyl hydroxide is effective. Runjie Napowei eye drops can safely and effectively relieve some symptoms and signs of visual fatigue within 14 days. ⑤ Traditional Chinese medicine. ⑥ Auricular acupoint pressing and acupuncture. From this study, we can see that ginger can increase blood flow rate and is safe and beneficial for improving eye fatigue and shoulder stiffness, especially for women under 51 years old. These benefits are crucial to improving the quality of life, and ginger extract also has broad application prospects in this regard.
