Best herbs for Eye health
Eye health encompasses a broad range of factors beyond the mere absence of eye diseases or vision impairment. Historically, definitions of eye health have focused on biomedical classifications and levels of vision loss, which facilitated the quantification of avoidable vision loss and the design of targeted interventions. However, contemporary definitions emphasize a more holistic approach, recognizing eye health as integral to overall physical and mental well-being across all age groups and life stages. This broader perspective includes the prevention and treatment of eye diseases, the promotion of good vision, and the enhancement of quality of life through comprehensive eye care services. The Lancet Global Health Commission on Global Eye Health has further advanced this understanding by framing eye health as a critical component of sustainable development, contributing to goals related to poverty reduction, education, economic growth, and equity. This shift underscores the importance of integrated, people-centered eye care that addresses the full spectrum of eye health needs, from promotive and preventive measures to curative and rehabilitative services.
1. Indian gooseberry
Indian gooseberry, also known as amla, is highly beneficial for eye health due to its rich content of antioxidants, particularly vitamin C, which plays a crucial role in maintaining eye health. The high antioxidant properties of amla help in reducing oxidative stress, which is a major contributing factor to age-related eye diseases such as cataracts and macular degeneration. Additionally, amla’s anti-inflammatory properties can help in reducing inflammation-related eye conditions. Its bioactive compounds, such as polyphenols and carotenoids, have been shown to provide protective effects against various ocular abnormalities by mitigating the production of reactive oxygen species and suppressing inflammatory markers. Regular consumption of amla can thus be a natural way to support and maintain healthy vision.
What Research Says?
- According to the findings from research conducted by Journal of Functional Foods, Indian gooseberry extract (IGE) has demonstrated protective effects against retinal degeneration in a mouse model of Alzheimer’s disease. The extract inhibited oxidative stress and reduced histological changes in retinal tissue, indicating its potential to protect against retinal damage through its antioxidant properties.
How to consume
Indian gooseberry can be consumed in several ways. One popular method is drinking fresh amla juice daily, which can be made by blending the fruit with water and a touch of honey for sweetness. Alternatively, you can eat raw amla as a snack or add it to salads for a tangy twist. Amla powder is another versatile option; it can be mixed into smoothies, yogurt, or even sprinkled over dishes.
Potential Side Effects of Indian Gooseberry
High vitamin C content may lead to digestive issues such as acidity, nausea, stomach cramps, and diarrhea. The fruit’s fiber content, while beneficial in moderation, can cause constipation or exacerbate gastrointestinal problems when consumed in large amounts. Long-term excessive intake may also result in dry skin, dehydration, and weight loss.
Who Should Avoid Indian Gooseberry
Those with bleeding disorders or scheduled for surgery should be cautious, as amla has antiplatelet properties that may increase the risk of bleeding. People with hyperacidity or gastrointestinal issues may find that amla exacerbates their symptoms due to its acidic nature. Additionally, those with low blood sugar levels or taking anti-diabetic medications should monitor their blood sugar closely, as amla can lower blood sugar levels further. Pregnant and breastfeeding women are advised to consult their healthcare provider before consuming Indian gooseberry, as its effects in these conditions are not well-studied.
Interaction with Medications
Indian gooseberry can interact with several medications, potentially leading to adverse effects. It may lower blood sugar levels, which can be problematic for individuals taking diabetes medications, as it could cause hypoglycemia. Additionally, its antiplatelet properties may increase the risk of bleeding when combined with anticoagulant or antiplatelet drugs.
2. Turmeric
Turmeric, known for its active compound curcumin, offers significant benefits for eye health due to its potent anti-inflammatory and antioxidant properties. Curcumin helps in reducing oxidative stress, which is a key factor in the development of various age-related eye diseases such as cataracts and macular degeneration. The anti-inflammatory effects of turmeric can also alleviate symptoms of dry eye syndrome and other inflammatory eye conditions. Additionally, turmeric’s ability to inhibit the formation of new blood vessels can be beneficial in managing diabetic retinopathy, a condition characterized by abnormal blood vessel growth in the retina. Incorporating turmeric into the diet or using it as a supplement may thus provide a natural approach to maintaining and improving eye health.
What Research says?
- According to studies performed by Molecular Nutrition Food Research, Curcumin has shown beneficial effects on multiple retinal diseases, such as diabetic retinopathy, glaucoma, and age-related macular degeneration, due to its antioxidative and anti-inflammatory properties.
