Hayfever is a condition that is expressed in the mucus membranes of the head, but has its roots in the liver and intestine, so our treatment has to ensure they are working well first. Remedies such as Aralia, Arum triphyllum, Arundo, Euphrasia, Rosa damascena, Sabadilla, Sinapis nigra and Wyethia can give great help.
For both hayfever and allergies in general we shall study for example Adrenalinum, Cortisol, Oxytocin, Histaminum, also Allicin and Sulphoraphane, as in allergies the body is over-reacting to substances that should be harmless, even foodstuffs.
