Organon Aphorism §268

The other exotic plants, barks, seeds and roots that cannot be obtained in the fresh state the sensible practitioner will never take in the pulverized form on trust, but will first convince himself of their genuineness in their crude, entire state before making any employment of them.

Samuel Hahnemann, Organon of Medicine, 6th edition (Boericke translation, public domain).
