Essence.
These are pieces similar to aristolochia, but smaller; they have the same power, but better. Cetvar root grows with aconite, and aconite plants weaken from its proximity. Ibn Masarjawayh claims that the action of the citvar root is similar to the action of the scorpion-shaped melon, but that it is weaker. I say: if he understands that the citvar root is weaker than the dormer, then he is wrong in his assumption, and if he understands that the dormer is weaker, then he is not far from the truth. I think that Ibn Masarjawayh has enough experience to discern this, and besides, these words do not go back to a source that can be relied on. He knows that the citvar root is opposed to aconite. How can he be weaker than the dormer?
