Herbal Supplements |
The Good, The Bad, The Ugly |

If you are a regular radio listener or tele-radyo viewer, station-scanning will inevitably bring you to one selling herbal or dietary supplements, likely touting a cure-all for many of the aches and pains and maladies of daily life: headaches, tiredness, dysmenorrhea, asthma, arthritis, hypertension, asthma, high cholesterol, diabetes, etcetera, some claiming disappearance of cysts and regression of tumors; or the commerce of skin whitening and height-enhancing products feeding off the cultural stigmas of dark skin and short stature. Listen a little bit longer and you will likely hear a testimonial or two, one boasting to have discontinued all prescription medicines in lieu of their newly discovered herbal miracle. The adverts will be embellished with words like "pure, 100% natural, and safe"; many will throw in "antioxidant!"; maybe a claim of "FDA approved", real or not; "holistic" is a favorite; one or two, a money-back guarantee. And you're slowly getting hooked, and thinking: "Wow! Maybe this is worth a try!. . . " Then you hear this: Mahalagang paalaala, ito ay hindi gamot at In English, it translates into: An important reminder. This product is not a medicine and should not used as treatment for any kind of ailment or malady. It is the obligatory disclaimer, which, almost always, will speed through with an unintelligible Tagalog garble. (If there is a "speed law" for talking too fast, this will merit a speeding ticket.) It's not meant to be clear, but just to fulfill the requirement of law, to replace the "No Therapeutic Claims" or "No approved Therapeutic Claims" disclaimer. It matters not, anyway; by that time, you're hooked, and ready to shell out your hard-earned money on this wow-of-a-product. Adverts, testimonials and messengers Adverts sell and tout products for almost every imaginable malady, sequing into cautionary reminders for those dreaded condtions: diabetes, stroke, heart attacks, kidney failure, or dialysis, almost always embellished with a paella of New Age come-on words: "Holistic, pure, 100% natural, probiotics, antioxidants." And, of course, there are the testimonials. It matters not that the public is forewarned with "No Therapeutic Claims" or "Mahalagang Paalala" warnings—the testimonial is the hook that win the gullible, the hopeful, and the desperate over. Of course, there is also the problem with the messengers: "Doctors", real or dressed up in their clinical white lab coats with stethoscopes slung around the necks, celebrities and celebrity newscasters who use their image and popularity delivering their 30-second endorsements of herbal products and supplements. In my small and informal boondock survey, "doctors" rate high in credibility, over 90%: "Pag sinabi nang doctor, totoo iyon. Magsisinungaling ba ang doctor? Celebrities are a not too distant second. In a study on motivations to herbal supplement use, positive testimonials and endorsements by celebrities and healthcare professionals (41.46% and 12.66% respectively) added up to 54% (10). I have often wondered if the "messengers" ever vet what they sell, or just read off written advert text. Or are "messengers" ever vetted? Once, after a half-hour of agonized listening to medical misinformation, I texted the station's number and asked: Why do you allow a guest speaker to spew such medical falsities. The reply: I'm not responsible for what they say. I am only in charge of inviting the guests. The good, the bad, the ugly. The cost and side-effects of prescription pharmaceuticals and the allure of alternative medicine have caused an burgeoning interest in herbal medicine. In the Philippines, unfortunately, herbal medicine, long in the purview of albularyos, medicos, and alternative healers, has been slowly disappearing, taken over by the commercial entrepreneurs and cottage industry of herbal production,the latter boosted by home-based capsule formulations of medicinal plants, such as malunggay, luyang dilaw, banaba, insulin plant, and many herbal teas. Yes, we are surrounded by the good. Well, not in the flora-deprived concrete-paved environs of urban-suburban existence, where medicinal plants are packaged into a commerce of herbal supplements, often expensive, sometimes unaffordable, invariably promising too much, but all labeled with "No Therapeutic Claims". But in the provinces, there are Edens of herbal plenitude of plants, weeds, leaves, roots, and fruits with medicinal benefits, mostly trampled on, unappreciated for its many health benefits, left to the fauna to feast on the flora. Flavier's list of ten medicinal plants—akapulko, ampalaya, bawang, bayabas, lagundi, niyog-niyogan, pansit-pansitan, sambong, tsaang-gubat, yerba buena—which was suppose to provide a legitimizing jump-start to a Philippine alternative movement, with "rolling stores" to bring accessible herbal products to the boondocks, sputtered, stalled, and died. A few are struggling to survive through the commerce of capsulized products. The Philippines ranks 5th in the number of plant species and maintains 5% of the world's flora. In my two decades work on compilation of medicinal plants in the Philippines, more than 1500 at present, I have plowed through hundreds of thousands of scientific studies on medicinal plants' phytoconstituents, biologic activities, and medicinal properties, which included many clinical trials, affirming and supporting their traditional medicine use. In countless eureka moments I found myself wowed, but at the same time saddened at the unexplored potential of hundreds of herbal medicinal plants, the science and thousands of studies wasted and dumped into a dustbin of to-be-forgotten-benefits. The bad I will dare say, it is the rare breed of physician who will have the knowledge or the time to advise patients on their use of medicinal plants and supplements. Sadly, many in the medical community look at herbs and supplements with disdain. It is often a jaundiced and biased opinion, often based on ignorance, rather than intelligent appraisal. And furthermore, in the time-constrained visit to the doctor, there is little or no time to be spent advising on herbal or supplement use. Packaging and labeling of herbal and medicinal supplements are also woefully lacking in information. Only a few phytoconstituents and contents. Some claim only proprietary ingredients. Many just list various plant constituents without specifying specific plant parts used. I have not been able to find any independent studies done on supplements confirming actual constituents and quantified ingredients. The ugly Caveat emptor In the U.S., in an investigation of popular herbal supplements sold by prominent national retailers (GNC, Target, Walgreens and Walmart), four of five products tested showed none of any of the herbs listed on the labels. A product claiming to promote "physical endurance and vitality" contained only powdered garlic and rice. Some were found contaminated with unlisted ingredients, including some that may be hazardous to people with allergies. In another study, 60% of herbal products tested contained plant substances not listed on the label, and 20% containing fillers of rice, wheat, or soybeans. Some found no plant DNA bar-coding (short gene sequences that indicate a particular species), which manufacturers countered as having been destroyed by processing. Another study found 50% contained no active ingredient, 30% contained contaminants and fillers. The question was raised: If such well-known brands are found fraudulent, could the problem infect the entire industry? Those were U.S. studies. Can such fraudulent enterprise exist in the Philippines? Unfortunately, dietary and herbal supplements do not undergo the stringent regulatory oversight given to prescription pharmaceuticals. While the FDA publishes advisories, debunkings, and listing of unregistered products, the FDA does not test dietary or herbal supplements for alleged contents or verify claims on biologic activities before they are sold to consumers. The FDA has publishes advisories (FDA Advisory: 2013-063: published 12 December 2013, is a cautionary read that still applies today.) and 101s on High-Foods (Draft Approach on High-Risk Foods). Most of the people contemplating use of a herbal supplement do not have the time nor the ability to sift through the morass of information, which are not user friendly nor info-helpful for the particular supplement being searched. In the battle of testimonials, social media, and adverts on one side and a few exasperated rants of skeptics and advisories on the other side, the testimonial-gang wins hands down. Plant Pharma There should be no debate as to the deserved status of herbal medicinal plants—Plant Pharma —in medical therapeutics. It should be included in curriculum of Medical education, to be studied, taught, appreciated, and fostered for its myriad of potential benefits, rather than suffer the chronic disdain birthed from ignorance and prejudice of the medical establishment. When I ask the often-idle and underutilized barangay health workers what and how they teach the local folk on the use of medicinal plants, the response, almost always: We don't know how to teach and what to teach. These health workers should be mobilized and schooled into the preparation and use of decoctions, infusions, tinctures, ointments, and poultices, then unleashed to educate the rural and boondock populations. The early promise of "rolling stores" that will bring accessible and affordable herbal medicinal plants to the ruralfolk sputtered and died before it could take roots. Entreprenurial commerce reincarnated the noble idea into the unregulated gold-mine industry of herbal supplements with adverts and testimonials teeming and oozing with promise of cure for this-and-that and whatever-malady you're afflicted with. There should be regulations on the legality and validity of claims made regarding herbal and dietary supplements. There should be banning of fake reviews and testimonials. With their motivating powers, messengers of reviews, testimonials, and adverts—celebrities, white-coat sellers, and commentators—should know what they are selling, rather than just reading scripted texts promising miracle cures. Owners or managers of herbal and supplement products should be prohibited from writing or controlling content of reviews and testimonials on their own products. Material connections between endorser and relationship to the company should be disclosed. Herbal products/supplements should be submitted to an FDA accredited laboratories for qualitative and quatitative verification of alleged ingredient list and net contents, with web-based accessibility of results, ratings, reviews, and advice in a language comprehensible to herbal supplement users. But, yes . . . wishful thinking, all. And in the chaotic, unregulated ecosystem of herbal and medicinal supplements, fake reviews and bogus testimonials, and the coming of AI-generated testimonials, well . . . good luck. Alas, for now we're on your own, to figure out what is safe, what works, which is true green or snake oil. Although use of commercial herbal products is faith-based, it won't hurt to educate yourself. Despite its pockets of misinformation, the Web is still a great source of readily available info on hundreds of herbal medicinal plants, possible contraindications or interactions with prescribed medications, and forums, blogs, and postings on their pros and cons and suspected snake oils and scams. Read the labels and watch for side effects or allergic reactions. Mention your herbal supplement use on your next healthcare provider visit, who might have time time or knowledge to advise. Choose a reputable manufacturer's brand, preferring standardized products and brands that provide information on ingredients, side effects, and precautions (good luck on the search). And click-off testimonials of miracle cures or those that promise too much. If the herbal supplement delivers on its promise, well and good; but many do not have immediate discernible effects, and many will not have clinically measurable long-term benefits. If it is a sham product, at the very least, it provided for expensive urine. I am still hopeful for a plant-based renaissance in health care, for affordable plant pharma to benefit one and all, but more so, the poor and marginalized who are barely surviving with hand-to-mouth existence, dreading the visitation of illness and unaffordable therapies of pharmaceutical and mainstream medicine. It might require a seismic shift in the paradigms of teaching, to bring medicinal plants into the curiculum of medical education, to merge folklore with science, to merge traditional medicine with western medicine, to encourage scientific studies on hundreds of endemic flora, to mobilize barangay health care workers into the rural and boondock areas to teach the wildcrafted use of plants. A hope lingers. A dream continues. |
