The infiltration of pseudoscience and simply bad medicine into mainstream medicine continues. Hospitals are an easy breech point because they are run by administrators who may have more talent and interest in marketing than in science. Many hospitals in my area, for example, proudly display their “integrative” centers, offering nutrition advice and massage alongside more dubious offerings, such as reflexology and reiki.
So-called “alternative” treatments are tempting because they are often not covered by insurance, and so patients will have to pay cash for them, and they are often inexpensive to run – so they are a nice cash cow for hospitals.
The Wall Street Journal reports another, more serious, chapter in this infiltration – the opening of Chinese herbal clinics, specifically in the Cleveland Clinic. The article itself is reasonably balanced, and lacks the gushing anecdotes that most such pieces have, but could certainly have been more hard-hitting in terms of the serious problems with herbal medicine.
A correspondent asked me to review the book What to Expect When You’re Expecting by Heidi Murkoff and Sharon Mazel. She wrote “I’m very worried about this book.”
She had just seen an NPR article about the book and was alarmed because it provided an excerpt from the book recommending that patients with morning sickness “Try Sea-Bands” and “Go CAM Crazy.” She knew from reading SBM and other science blogs that “going CAM crazy” is not a good idea. She was savvy enough to search Google Books with the title and “CAM” and found more alarming advice. (more…)
David Kroll’s recent article on thunder god vine is a great example of what can be learned by using science to study plants identified by herbalists as therapeutic. The herbalists’ arsenal can be a rich source of potential knowledge. But Kroll’s article is also a reminder that blindly trusting herbalists’ recommendations for treatment can be risky.
Herbal medicine has always fascinated me. How did early humans determine which plants worked? They had no record-keeping, no scientific methods, only trial and error and word of mouth. How many intrepid investigators poisoned themselves and died in the quest? Imagine yourself in the jungle: which plants would you be willing to try? How would you decide whether to use the leaf or the root? How would you decide whether to chew the raw leaf or brew an infusion? It is truly remarkable that our forbears were able to identify useful natural medicines and pass the knowledge down to us.
It is equally remarkable that modern humans with all the advantages of science are willing to put useless and potentially dangerous plant products into their bodies based on nothing better than prescientific hearsay. (more…)
One of my earliest lessons as a pharmacist working in the “real world” was that customers didn’t always act the way I expected. Parents of sick children frequently fell into this category — and the typical vignette went like this for me:
- Parent has determined that their child is sick, and needs some sort of over-the-counter medicine.
- Parent asks pharmacist for advice selecting a product from the dozens on the shelves.
- Pharmacist uses the opportunity to provide science-based advice, and assures parent that no drug therapy is necessary.
- Parent directly questions the validity of this advice, and may ask about the merits of a specific product they have already identified.
- Pharmacist explains efficacy and risk of the product, and provides general non-drug symptom management suggestions.
- Parent thanks pharmacist, selects product despite advice, and walks to the front of the store to pay.
In many ways, a pharmacy purchase mirrors the patient-physician interaction that ends with a prescription being written — it’s what feels like the logical end to the consultation, and without it, feels incomplete. It’s something that I’m observing more and more frequently when advising parents about cough and cold products for children.
I’ve previously described the consequences of acute and chronic sun exposure, and the rationale for topical sunscreen products. But wouldn’t it be easier to just take a pill that can boost our skin’s resistance to to the harmful effects of the sun? Is it possible to get all the benefits of sunscreen without the bother of creams, or even clothing? (more…)
The past two months have been my first time working in the hospital, as a third-year medical student in my Internal Medicine clerkship. It’s been exciting not only to see how medicine works but to be a part of the action! It really is striking to see the dramatic increases in proficiency and confidence with each stage of the training. From junior student to acting intern to intern to resident to chief resident and eventually to attending, each year brings both more responsibility and more competence. Importantly, physicians-in-training also get very efficient in seeking out and communicating information. Just like SBM editors read widely and blog prolifically whereas I struggle to put together one post a month, experienced clinicians have responsibility for dozens of patients at a time whereas I feebly tag along with one or two each day. Watching my elders on the medical team, I feel excited about how much smarter and more effective I will become as I progress through my training.
Anyway, I want to share an interesting sight in my hospital last month. There were three 3-foot posters on tripods prominently displayed in the hospital lobby, in the cafeteria, and in other public places. The first one read: (more…)
Peanut allergy is uncommon but devastating. Even a tiny trace of peanut can cause an anaphylactic reaction and death. That’s why labels specify “produced on shared equipment with nuts or peanuts” or “produced in a facility that also processes nuts.” There is no effective treatment: patients have to rely on avoiding peanuts and carrying emergency epinephrine injectors. Parents of peanut-allergic children live in fear that their child will be inadvertently exposed at school or at a friend’s house. Wouldn’t it be great if we could fix it so they could eat peanuts with impunity?
There is a ray of hope. Studies are underway on a Chinese herbal medicine (FAHF-2) that shows promise. I generally shy away from Chinese herbal remedies, because they are marketed without adequate testing and the products are not quality controlled. The typical course of events is (1) a preliminary study or a history of use in China, (2) marketing in the U.S. with overblown claims.
This is different. (more…)
