title: [Trends in Google searches on complementary and alternative medicine].
abstract: The aim of this article is to evaluate the interest in complementary and alternative medicine (CAM) therapies using Google Trends in spanish-speaking countries.
  
  
  
  An observational study was conducted using GoogleTrends. The search volume of 34 CAM therapies in spanish were evaluated globally and in 21 spanish-speaking countries. Also, the relationship between the median of the most popular searches and the gross domestic product (GDP) per capita in each of the countries was evaluated using Spearman's test.
  
  
  
  A decreased trend in search volume was observed in homeopathy, herbal medicine, acupunctureand sensory therapies; and an increasing trend in chiropraxy. A direct association was observed between the GDP per capita and the median between the most popular CAM therapies, this relationship was no significant (p = 0.432).
  
  
  
  The interest in CAM therapies shows temporal and geographic variations that must be studied in depth. These results can be used for the establishment of an international monitoring for the use of CAM therapies.
