Hope things continue to improve at least a bit, so you can get back home.
I get studies emailed to me automatically by the Canadian Medical Association.
Here's an interesting one I got today.
Herbs effective in low back pain
Clinical question
Are herbal medicines more effective than placebo in treating adults with low back pain?
Bottom line
If these authors have included all the relevant studies, it appears that there is modest evidence that herbal remedies (oral Harpagophytum procumbens [devil's claw] and Salix alba [white willow bark], as well as topical Capsicum frutescens [cayenne]) alleviate acute episodes of chronic nonspecific low back pain in adults. In general, the reporting of the trials included in this systematic review was poor. Finally, this body of literature is prone to bias in favor of publishing positive results. (LOE = 1a-)

Synopsis
The authors of this Cochrane review searched multiple databases for randomized trials comparing ingested or topical (but not smoked) herbal medicines with placebo or other therapies in the treatment of adults with low back pain. The authors report a limited search for unpublished trials by contacting individuals with expertise in herbal remedies and low back pain. Two authors independently assessed articles for inclusion and extracted the data. Additionally, 2 authors independently assessed the methodologic quality of the included studies. Finally, they also rated the overall strength of evidence. Strong evidence was defined as consistent findings among multiple high-quality studies, and moderate evidence required consistent findings among low-quality studies or one high-quality study. The authors used a consensus process to reconcile discrepancies. They identified 10 trials (1567 patients) that were generally of limited quality. They found 3 studies demonstrating strong evidence that 50 mg devil's claw per day was more effective than place bo. One trial found it to be equivalent to 12.5 mg rofecoxib (Vioxx) per day. The authors found modest evidence that white willow bark (120 mg to 240 mg daily) provided short-term pain relief, comparable with 12.5 mg rofecoxib. Three low-quality trials found topical capsaicin (cayenne) was better than placebo and equivalent to a homeopathic remedy. The authors don't report enough data to calculate numbers needed to treat or to harm.
Thanks. Interesting read.
