Up until a few hundred years ago, an abundance of these herbs were only available to Emperors, Empresses and the elite.
Those who followed the Daoist path, who desired to take multiple herbs in large quantities would seek the sacred mountains where they could forage and live a life of hermitage.
We live in a golden age where we cannot only access these treasured herbs in abundance, but also grow and forage them in ways that remain true to the philosophy that created reverence for these herbs.
