Full moon limpias are offered on the evening of the full moon with the strong energies of Nana Metzli (Grandmother Moon). These raw energies and moon beams transmit power into the limpia and medicine tools and thus further encourages in ones healing.

Reasons for a limpia range from needing to discover the root cause of illness, to anxiety, fear, negative self-talk, anger, or even envy (either directed towards oneself or that one feels towards another person). As well sometimes one needs a cleansing to remove obstacles in their relationships, or to letting go of unforgiveness or grudges (either towards another person or towards oneself.)
