H. P. Blavatsky had written: ‘Plants also have like mystical properties in a most wonderful degree, and the secrets of the herbs of MYSTICAL PLANTSdreams and enchantments are only lost to European science, and useless to say, too, are unknown to it, except in a few marked instances, such as opium and hashish.

Yet, the psychical effects of even these few upon the human system are regarded as evidences of a temporary mental disorder. The women of Thessaly and Epirus, the female hierophants of the rites of Sabazius, did not carry their secrets away with the downfall of their sanctuaries. They are still preserved, and those who are aware of the nature of Soma, know the properties of other plants as well.” (Isis Unveiled.)
