canker which occurs near the eyes and in the breasts, as Avicenna says. If a person were to sleep in the shade of this tree, it would be the cause of producing many illnesses.

If the juice of the same tree be given together with vinegar in the fevers that come with shivering and coldness, it will promptly help with them. If the kernels of this nut be eaten with juice of rue, it will help with every poison, and if they be eaten regularly, they will generate hot choleric humours, especially in the hot complexes. If the kernels of walnut be pounded with honey through them, it will help with the hard apostumes that are produced by the melancholic humour, as we have said.
