Ginkgo, Garlic, and Ginseng Research on Eye Health and Dementia

ginkgo-garlic-and-ginseng-research-on-eye-health-and-dementia.jpgThree time-tested supplements stand out as champions for eye and brain health: garlic, ginseng, and ginkgo. Research on these supplements backs up why they have been used for thousands of years. Garlic plays an important role in all three major traditional medicines–Traditional European Herbal Medicine, Ayurveda, and Traditional Chinese Medicine. Ginseng and ginkgo are crucial herbs in Traditional Chinese Medicine. Do these supplements work? Are they beneficial for aging brains and eyes? What does the research show? Brain and eye health are closely connected. The optic nerve of the eye is actually neural tissue. Heart and cardiovascular health are also closely tied to the brain and eyes. Oxidative stress can damage all three systems. What role could garlic, ginseng, and ginkgo play in counteracting diseases such as dementia, cataracts, macular degeneration, and glaucoma?

Diabetic Retinopathy & Diabetic Cataracts

Diabetic retinopathy is common in diabetes, often resulting in retinal damage if left untreated. North American Ginseng research found benefits for the retina in diabetic rodents. Also, the heart and circulatory systems were protected. The main reason was likely ginseng’s antioxidant properties.1Cataracts are a common side-effect of diabetes. The partial or main reason is glycation, the accelerated binding of sugar and protein molecules in the lens. Ginkgo biloba extract was found to have a protective effect on diabetic cataracts in the laboratory.2

Glaucoma

Glaucoma is a serious eye disease that usually strikes seniors. Most glaucoma patients have elevated intraocular pressure in the eye. Some glaucoma patients have normal or low-tension glaucoma. Regardless, glaucoma if left untreated damages the optic nerve and other parts of the eye. Glaucoma leads to tunnel vision and may cause near or total blindness. Even with treatment and reduced or normal intraocular pressure, glaucoma may continue to progress. This can be due to poor circulation and lack of essential nutrients reaching the optic nerve. A 2012 review looked at ginkgo and glaucoma.3 Vitamins C and E, for example, are antioxidants. However, antioxidants in ginkgo called “polyphenolic flavonoids” can act on the mitochondrial level. The mitochondria are like batteries for cells. Malfunctioning mitochondria are present in several diseases, especially neurodegenerative diseases. Studies have found damaged mitochondria in glaucoma patients.4 Oxidative damage to the mitochondria likely plays a role in glaucoma. Thus, ginkgo may prove helpful as an adjunct therapy. Glutathione — also called “the anti-aging antioxidant” — is a cellular detoxifier and broad-spectrum antioxidant. The body produces glutathione. However, it requires the “building blocks,” including several amino acids, selenium and Vitamin C. Our diets tend to have insufficient L-cysteine, which is one of the building blocks. Additionally, pollution, poor diet, a sedentary lifestyle, toxins, stress, infections, aging, and more can reduce glutathione levels. Glaucoma patients have low glutathione levels, according to several studies.56 Research has found that garlic can raise glutathione levels in the body. 78

Cataracts

In the laboratory, researchers can induce cataracts by injecting rodents with a mineral. In a small but well-controlled study, a group of rats were injected with both the mineral and a garlic extract solution.9 The control groups had no treatment, the mineral, or the garlic. Rats injected with only the mineral developed cataracts as expected. None of the other groups developed cataracts. Therefore, garlic may be a useful herbal remedy for preventing the formation of cataracts.

Corneal Damage

After an eye wound or corneal surgery, the cornea needs time to heal. An animal study found that a derivative of ginseng promotes corneal wound healing.10 Applying ginseng gintonin eyedrops to rabbits with corneal damage promoted rapid recovery. Corneal cells died at a slower rate, and new corneal cells proliferated.

Dementia and Alzheimer’s Disease

A 2010 review of research on ginkgo biloba and Alzheimer’s disease found that ginkgo was better than a placebo.11 Another study found that ginkgo appeared to delay the onset of Alzheimer’s disease.12 Garlic is being researched for its neuroprotective properties.13 And research into ginseng is finding many neuroprotective benefits.14

How Much to Ginkgo, Ginseng & Ginger Take or Eat

ginkgo-garlic-and-ginseng-research-on-eye-health-and-dementia-1.jpgBlood Thinning Warning: All three of these products can thin the blood. This means they can reduce the blood’s ability to clot. For people who are not taking blood thinners, this blood-thinning effect could prevent a stroke. However, if you are taking a blood-thinning medication such as warfarin (Coumadin), talk to your doctor before taking these supplements. Also disclose all your supplements if you need surgery.15 These same guidelines apply to eating or drinking large quantities of garlic. These products can be eaten as an ingredient in cooking, or taken in various supplemental forms. Michael Edson, co-founder of Natural Eye Care, will recommend these daily dosages in his upcoming book about Natural Brain Health, and discussed in his and Dr. Grossman’s recent book “Natural Eye Care: Your Guide to Healthy Vision and Healing“:
  • Garlic (optimized) – 1200 mg per day
  • Ginseng (Panax) – 500mg – 1,000 mg per day of Asian ginseng (panax ginseng) extract (root)
  • Gingko Biloba- 120mg – 240 mg per day

I Spy a Stye in Your Eye

Image
Written by Dr. David Evans Last modified on August 6, 2018 What’s that small, red, pimple-like bump on your eyelid that’s causing so much discomfort? It’s probably a stye (sometimes referred to as a sty or hordeolum). Besides being difficult to say 5 times quickly, an eye stye is a type of localized infection that can occur along the base of your eyelashes or underneath your eyelid. Styes that form along the base of the eyelashes are called external styes. They typically occur as a result of an infected eyelash hair follicle and look like the type of pimple that occurs when your pores are clogged with dirt and oil. Styes that form inside the eyelid are called internal styes. Similar to external styes, they are caused by an infection of an oil-producing gland behind the eyelid rather than an eyelash hair follicle. Internal styes result in generalized swelling of the eyelid rather than forming a pimple-like bump. Stye Symptoms As a stye develops, you might begin to experience pain

Post-LASIK Refraction and Pregnancy – Much Ado About Nothing?

Image
Written by Dr. David Evans Last modified on August 23, 2018 During pregnancy, women experience a drastic shift in their hormonal balance that has a ripple effect throughout the body. The spike in hormones like progesterone, estrogen, prolactin, oxytocin and relaxin are all important for a healthy pregnancy, but these increased levels can also impact gastrointestinal processes, blood pressure, skin pigmentation and, you guessed it, ocular health. Due to refractive changes that often occur during pregnancy, most refractive surgeons advise against LASIK during pregnancy, instead suggesting women wait several months after giving birth before considering treatment. Women who have already undergone LASIK may then wonder if the changes in ocular health that can occur during and after pregnancy impact post-LASIK refraction. New research presented by John Kanellopoulos, MD, New York University Medical School, NY, and LaserVision.gr seems to throw cold water on any such concern. The Eyes an

Overuse of Contact Lenses

Image
How do make sure you aren’t overusing your lenses? Most people who have prescription eye glasses prefer wearing contact lenses. It’s not only comfortable but it also doesn’t alter your natural look. Though contact lenses are convenient they shouldn’t be used extensively. Overuse of contact lenses can cause serious damages to your eye. If you are not following the 18 hour week rule, then you could be overusing your contact lenses. In other words you must take out your contact lenses for at least 18 hours a week. Here are some symptoms which are indications that you are using you have your lenses on longer than you should, and you need to consult your eye doctor immediately: Pain and redness in the eye Itching when you remove your lenses Increased mucous secretion in the eye Decreased vision Photophobia or light sensitivity Tearing Inability to remove your lenses because they are stuck in the eye   Your eye needs direct oxygen to ‘breathe’ and remain healthy.
