Herbal Remedy for the Flu?

Sunday, August 28, 2011 // Uncategorized

Some drugs are derived from plants.  This is a summary from Journal Watch about research from China where Tamiflu (Oseltamivir) was compared against an herbal remedy for the treatment of flu symptoms.  It’s hard to know where this will lead, but other flu drugs are needed to combat the development of resistance.  The abstract from The Annals of Internal Medicine follows.

 

Chinese Herbs as Efficient as Oseltamivir for Shortening Flu Symptoms
Traditional Chinese herbal therapy resolves fever in influenza as quickly as oseltamivir, according to an Annals of Internal Medicine study.
Researchers studied some 400 adults and adolescents in 11 Chinese hospitals who had uncomplicated 2009 H1N1 influenza A. Patients, who remained in the hospital for quarantine purposes and not the severity of their illness, were randomized to one of four groups: maxingshigan-yinqiaosan, oseltamivir, maxingshigan-yinqiaosan plus oseltamivir, or no treatment. (Maxingshigan-yinqiaosan comprises 12 herbs, including ephedra, which is restricted in the U.S.)
The median time to fever resolution was significantly shorter with oseltamivir (20 hours), maxingshigan-yinqiaosan (16), and combination therapy (15) than with no treatment (26). Symptomatic improvement did not differ among the treatment groups. Two patients using maxingshigan-yinqiaosan had nausea and vomiting.
The authors conclude that the herbal treatment can be used as an alternative when oseltamivir is not available.

Here’s the abstract from The Annals of Internal Medicine:

Abstract

Background: Observational studies from Asia suggest that maxingshigan–yinqiaosan may be effective in the treatment of acute H1N1 influenza.

Objective: To compare the efficacy and safety of oseltamivir and maxingshigan–yinqiaosan in treating uncomplicated H1N1 influenza.

Design: Prospective, nonblinded, randomized, controlled trial. (ClinicalTrials.gov registration number: NCT00935194)

Setting: Eleven hospitals from 4 provinces in China.

Patients: 410 young adults aged 15 to 59 years with laboratory-confirmed H1N1 influenza.

Intervention: Oseltamivir, 75 mg twice daily; maxingshigan–yinqiaosan decoction (composed of 12 Chinese herbal medicines, including honey-fried Herba Ephedrae), 200 mL 4 times daily; oseltamivir plus maxingshigan–yinqiaosan; or no intervention (control). Interventions and control were given for 5 days.

Measurements: Primary outcome was time to fever resolution. Secondary outcomes included symptom scores and viral shedding determined by using real-time reverse transcriptase polymerase chain reaction.

Results: Significant reductions in the estimated median time to fever resolution compared with the control group (26.0 hours [95% CI, 24.0 to 33.0 hours]) were seen with oseltamivir (34% [95% CI, 20% to 46%]; P < 0.001), maxingshigan–yinqiaosan (37% [CI, 23% to 49%]; P < 0.001), and oseltamivir plus maxingshigan–yinqiaosan (47% [CI, 35% to 56%]; P < 0.001). Time to fever resolution was reduced by 19% (CI, 0.3% to 34%; P = 0.05) with oseltamivir plus maxingshigan–yinqiaosan compared with oseltamivir. The interventions and control did not differ in terms of decrease in symptom scores (P = 0.38). Two patients who received maxingshigan–yinqiaosan reported nausea and vomiting.

Limitations: Participants were young and had mild H1N1 influenza virus infection. Missing viral data precluded definitive conclusions about viral shedding.

Conclusion: Oseltamivir and maxingshigan–yinqiaosan, alone and in combination, reduced time to fever resolution in patients with H1N1 influenza virus infection. These data suggest that maxingshigan–yinqiaosan may be used as an alternative treatment of H1N1 influenza virus infection.
