The health care reform debate that is currently being waged in Washington has led to a great number of discussions that have exposed the public's frustration with the business practices of the profiteering Big Pharma and Big Insurance industries. Our collective distrust of companies in these sectors has led many of us to seek out less expensive, at-home treatment methods for the diseases and disorders that affect many of us. Traditional herbal medicine provides us with the means to stick it to the fat cats and potentially find relief for pesky allergies, sleeplessness, depression, obesity, and a huge variety of other disorders. Our increasing focus on alternative and traditional means of self-medicating has definitely not gone unnoticed by supplement companies and entrepreneurs who can prey on the populist rage by essentially marketing whatever supplements, teas, and drugs they want however they want without much need to focus on accountability. I often comment on specific supplements or dietary modifications for specific diseases and disorders, but in this post, I would like to focus on the current reality of traditional herbal medicine in the western world.The drug industry in the western world has seen increased regulation and oversight in the past hundred years or so. M.D.s, the FDA, and pharmaceutical companies are increasingly focused on accountability in the litigation-happy United States. Therefore, the amount of research and development required to bring a seemingly effective new drug entity (new chemical compound with potential drug action) to market with little to no toxic side effects has dramatically increased, which is accompanied by more dollar signs than I can wrap my head around. 2003 estimates put the number at over 800 million USD, and now that number could be as high as 1.7 billion. The average timeline for bringing a new drug entity to market is approximately 12 years according to Covance Inc. Many pharmaceutical companies claim that 1 in 5000 of potential drug molecules will actually make it to market. It is important to note that marketing accounts for a large percentage of pharma expenditures. Specific numbers are hard to nail down, since it could potentially lead to very negative PR, but John Mack has provided some estimates in his blog on pharma marketing (Print ads, free lunches). However, another major cost for pharma companies is paying to screen the estimated 4999 failed drugs for every 1 successful one, potentially short patent lifespan depending on whether formulation and development takes 5 years or 20 years, and FDA approval as it relates to screening for all potential toxicities that may result from the drug. The end result for us consumers is a drug product or products that we can take to cure what ails us and the ever-important peace of mind that we're not going to lose a kidney or die from it. The public has spoken and the government now enforces that this must be true in order to gain FDA approval and the trust from M.D.s to prescribe the drug. This represents how Americans and other westerners insist that our drugs must be researched, developed, prescribed, and regulated. However, the costs of this type of system have gotten to be too large for many of us, especially those of us (5, 17, or 40 million, it's hard to tell these days) without insurance. Execs seem to be getting richer while we all broke the piggy bank about a year ago and are still sick. Enter herbal self-medication.
Traditional herbal medi
cines can be found all over the world with written records that predate the Shang dynasty (for you slackers that never learned your Chinese history that's 1700 to 1027 BC. I take that back. You're not really slackers, I didn't know that before today either). Potentially, no herbal tradition is richer than that of the Chinese herbalist. Hundreds of Chinese herbs have been recorded for use in the treatment of nearly every illness. However, in Chinese herbalism and that of other cultures, many herbal indications for use are accompanied by mechanistic explanations that include energy balance, spiritual manipulation, and other pseudoscientific ideas. Regardless of the mechanism of action, many herbals are still in use, because, well, many of them just work. In the modern world of molecular biology in the age of proteomics, we do not accept pseudoscientific explanations when our lives are on the line. In the western world, the FDA and M.D.s who may be exposed to liability suits are not willing to gamble without hard science to support the use of herbals. The integration of over-the-counter herbal medicine and supplementation into our current schedule of drugs for chronic conditions suggests the need to understand how herbal supplements or medications might interact with the drugs we're already taking such as lipitor, nexium, plavix, birth control (think: Surprise! You've got a bun in the oven), and potentially others. We also need to know how to dose herbal supplements. A mixed bag of tea from your neighborhood herbalist would likely make your primary care provider faint. How much of each active drug component are you getting and how often? Does it vary for each cup you drink? We require these answers before herbals can make it to the broader western market.Some companies have taken note of these requirements, and more importantly, the market size of our drug-reliant populous to capitalize on the huge variety of herbals that are currently in use. I would like to give a few examples of some herbal products that have begun the process of assimilating many of our American standards and regulations towards the production of viable drug products or supplements.
- Circumin is one of the key ingredients in turmeric. It is a staple in Indian and middle eastern cuisine for its color, flavor, and food preservation qualities. Over time, cooking with turmeric has been adopted in dishes throughout most of the eastern hemisphere. In traditional medicine, curcumin has been used to treat a huge variety of conditions, however it wasn't until the late 20th century that researchers began to investigate the biochemical mechanisms behind its efficacy. As of today, 3953 peer-reviewed papers are retrieved in a search for curcumin. From all of this research, we now know that curcumin has legitimate anti-inflammatory and anti-oxidant properties. These properties have been deemed so sufficient that there are now indications for dozens of western diseases including Alzheimer's disease and various forms of cancer. Several clinical trials have been completed for many of these indications, which means that there is real data to say how much curcumin is needed to achieve desired effects or toxic effects. In addition to its efficacy and minimal toxicity, foods made with turmeric are absolutely delicious, so search the googlewebs and find yourselves some recipes that you can work with. I even made chex mix with it this past weekend (spare me your Suzie Homemaker comments, everybody loves homemade chex mix).
-Artemisinin is a drug originally derived from Chinese wormwood which has been researched extensively for treatment of multi-drug resistant malaria. A derivative of artemisinin, artesunate, is now being researched for anti-cancer activity. As in the case of curcumin, the administration, distribution, metabolism, and excretion profiles have now been established which lets us know at what levels the compound is effective and what levels it is toxic.
In summary, herbal medicine traditions have a lot to offer in the way of effective natural products. I believe that this is an area where research dollars are appropriately being spent and should continue to be spent as there may be a good amount of "low hanging fruit" that turns out to be very good for us as potential supplements or drugs. However, validation of their use, as in the case of curcumin or artemisinin, is absolutely critical before self-medicating. This is especially true for those of us self-medicators without insurance who couldn't afford to have our unexpected drug-herbal reactions landing us in the hospital or the poor house.
