Recently, an old friend asked for some suggestions to protect her eyes from the “normal” visual decline associated with aging. Now, you’ve probably seen more than a few eye supplements at your local health food stores and pharmacies. And, most of these products contain similar ingredients such as beta carotene or pro-Vitamin A, copper, lutein, Vitamin C, zinc and so on. All of these nutrients and phytochemicals have been shown to benefit ocular function or health in one way or another. Having said that, some newer, far less common botanicals may provide additional protection. What’s more, these lesser known extracts are generally not found in nutraceutical formulas intended to support eye health.

The hair and skin care aisles of most health food stores are stocked with multiple creams, ointments and shampoos containing tea tree oil (TTO). In fact, the popularity of this native Australian export has even made its way into many mass market products. The crossover appeal of TTO is largely due to its documented antimicrobial and anti-inflammatory properties. In terms of practical applications, you’re likely to find TTO in remedies intended for acne prone skin, flakey scalps, gingivitis, toe nail infections and much, much more. But, just because tea tree oil is already well established in the beauty and health care sectors, doesn’t mean that there isn’t more to learn about it.

Today’s column is a response to the first health related question that was posed to me in 2013. During a recent consultation, a client inquired about the relative merits of an antioxidant compound commonly known as alpha lipoic acid. She noted that it’s frequently cited as one of the more potent antioxidants because it supposedly works in concert with other free radical scavengers such as glutathione and vitamins C and E. A recent review in Frontiers in Ethnopharmacology, a prestigious medical journal, supports this claim and details various others functions of a-lipoic acid including its ability to: a) chelate heavy metals; b) lower systemic inflammation; c) regulate gene expression; d) repair damaged proteins in the body.

In previous columns I’ve reported on the myriad of health benefits associated with turmeric extracts. Turmeric is probably best known as a component of curry, the traditional spice mix. However, among scientists, turmeric has been at the center of a love-hate relationship. In animal and in vitro studies, curcuminoids, antioxidant chemicals found in turmeric, have yielded very encouraging results in conditions ranging from autoimmune disease to dementia. Conversely, human trials have been far less consistent. Poor bioavailability is suspected as the primary culprit for the mixed findings in the human studies.

This year’s U.S. Open was marked by an unexpected medical headline. Venus Williams, a top ranked singles and doubles tennis player, announced that she was dropping out of the prestigious tournament because of debilitating symptoms relating to Sjogren’s syndrome. This autoimmune condition can manifest itself in a number of ways including musculoskeletal pain, persistent fatigue and severe dryness in the eyes and mouth. Thankfully, preliminary research points to several natural options that may help manage it.

Glaucoma is an eye condition which affects approximately 2.5 million men and women in the United States alone. It is characterized by increased inner eye pressure which can cause damage to the optic nerve and, thereby, result in vision loss. Fortunately, the combination of two nutraceutical ingredients has recently shown a reduction in intraocular pressure and an improvement overall eye health. (1) Read more »

Every once in a while I stumble across a “Where are they now?” program on television – a show documenting the lives of famous figures long after the spotlight has left them behind. A similar analogy could be made in the field of medicine. Select foods, medical procedures and supplements are always the recipients of media attention, but typically, it doesn’t last for very long. Does this mean that they’re no longer noteworthy once the spotlight has left them behind? Not from my perspective. That’s why I think it’s so important to continually update the columns I’ve written in the past. Read more »

Here’s an age old question: “Do you need to see something in order to believe it?”. The answer for some is “yes” and many require visual proof before they can accept something as legitimate or real. But there’s a whole other camp of thought. Some ascribe to the notion that you must first believe something is possible before you’re capable of seeing it. There isn’t a chance in the world that I can negotiate an agreement between these two schools of thought. However, a recent post on Twitter adds an interesting twist to this debate.

I watched a tragically sad piece on last weekend’s edition of the news program 60 Minutes. A series of patients with life threatening illnesses fell prey to a con artist who claimed to be able to heal them via natural remedies and stem cell treatments. This segment really hit home because it was a stark reminder that hope must be doled out judiciously. I believe the defining difference between well placed and false hope can be summarized in one word: evidence. Hope with a foundation that is evidence-based can be constructive and sometimes yields dramatic outcomes. On the other hand, false hope leaves patients vulnerable to exploitation and heart break.

When you travel there are many uncertainties that come with the territory. Cars break down at the most inopportune moments. Planes get delayed due to fog or security issues. Or perhaps the weather ends up deciding what attractions and sites you can or cannot visit. There’s a long list of unexpected complications that can rear their ugly heads while on the road. But there’s one thing I can always count on when we fly on an airplane or stay at a hotel: my eyes become dry and red. Most hotels and resorts are temperature controlled. The use of centralized air conditioning and heating ensures the comfort of guests and discourages the growth of bacteria and mold that can thrive in a more humid environment. In the grand scheme of things, vacation-related irritation of the eyes is a small price to pay for all of the pleasure that travel brings. However, for some people this sensation is chronic and unrelenting. Read more »

It’s difficult to conceive of any circumstance in which you’d purposefully eat the bark of a tree. Fruit from a tree, sure. Seeds? Possibly. Leaves? That might be pushing things a bit, but still plausible. But tree bark?! Technically, you can eat some varieties of tree bark in a survival situation. But I think most people would need to be in pretty dire straits to resort to that last ditch option. Fortunately for us all, a select group of scientists have been studying the health benefits of a specific tree bark in an attempt to derive a natural medicine from it. I’m pleased to report that their promising research now allows mankind to benefit from the goodness of tree bark by swallowing a pill rather than chewing on “tree skin”.

The most common form of vision loss associated with aging is called Age-Related Macular Degeneration (AMD). But like many other symptoms related to aging and genetic expression, the risk of encountering AMD can be reduced by adjusting one’s diet.

Several recent studies paint a clear picture about which dietary choices increase and reduce the risk of AMD. The newly released information is all the more important because of the discovery of a link between AMD and dementia/Alzheimer’s disease. (1) Both conditions share common risk factors such as cardiovascular disease and stroke, cigarette smoking and high blood pressure.
