the moon, the closest and most impactful celestial body, as well as the stars and the position of our planet in relation to them are taken into consideration by folk medicinal practices. they live on as the tradition of astrology, and every culture has its particular interpretations of the messages from the stars.

the cornerstone of this tradition in brazil is a book called the lunário perpétuo, originally a 15th century basque text, it was translated into spanish in 1594, portuguese in 1703. it is a summation and explication of popular and folkloric knowledge in the world, as it was before the era of modern science.
