This is prepared by combining bark of the oak tree with the skull of an animal.

Method of preparation

• Crush the oak bark
• The skull of any domestic animal may be used
• The link between the skull and bark is their calcium properties
• Further, it is the Ca formation and the skull formation that takes place first in the case of the development of the embryo
• Place the crushed oak bark in the brain cavity of the skull. Block the opening with a well shaped bone piece.
• Place the skull in a watery environment with weeds and plant muck which would have been damaged by the local diseases that effect the crop. This helps buildup the resistance of the plants and follows the principles of Homeopathy.
• It should be placed in a location where there is exchange of water such as rain drain/swamp.
• It should be noted that a foul smell is emitted on lifting the preparation and removing it from the skull
• This gradually reduces with drying after removal in a dark dry place
• Fungus may form
• Turn over frequently to correct the same
