Walnut is the remedy to help to protect against outside influences in general, and against the effects of change in particular. Walnut types are people who are fulfilling their purpose in life but who under the influence of the opinions, theories or beliefs of others, or of external circumstances in general, may be led to doubt their path. They are not like Cerato people, who actively seek out the opinions of others, but instead may be affected almost despite themselves.
As a remedy against the effects of change, Walnut is useful at all the transitions of life, from being born to teething to going to school to puberty to marriage to childbearing to retirement and beyond. It helps to break links with the past so that the person can move forward with confidence and without undue suffering.
Dr Bach's description - For those who have definite ideals and ambitions in life and are fulfilling them, but on rare occasions are tempted to be led away from their own ideas, aims and work by the enthusiasm, convictions or strong opinions of others. The remedy gives constancy and protection from outside influences.
