In Daoist philosophy, Autumn is the time of the Lungs (not only the physical lungs themselves, but the entire energetic Lung system, including the Large Intestine and the skin).
By supporting the Lungs and their function with herbs, breath practices and gentle movement we support their ability to let go of the gripes and judgements from the previous year and invigorate the body with new energy. The Lungs clear tepid water from the body so that we are not infected with attachments and toxins leading into Winter, so we are clear to go within and develop wisdom. Nourished Lungs mean a nourished colon, and if we eat well, include fibre, good quality protein and nourishing foods, then we can further let go of all the crap we no longer need. Some people enjoy using colonics and enemas to further support this, we encourage you to do these compassionately for your colon and be gentle if you do.
Finally, stay hydrated so your skin stays nice and moist. It gets dry in the Lung and therefore the skin in Autumn. Moisturise, eat hydrating foods, take Tremella, and Qi herbs to ensure your skin is nourished and supported.
