...is for people who know their own minds and think they know what is best for others. They are strong and enjoy the exercise of power, but in their negative states this can lead them to dominate others by force alone.
Tyrannical fathers and overbearing bosses are typical negative Vines, in that they expect absolute obedience from others and will not be overly concerned with winning hearts and minds as long as their orders are followed. In this respect Vine is very different from Vervain. Vervains attempt to convert others to their way of thinking; Vines are content with the simple imposition of discipline.
In their positive aspect Vine people make wise, gentle and loving guides who can inspire and lead others without resorting to force. When we fall into issuing orders the remedy is given to encourage us to show this positive side.
Dr Bach's description
Very capable people, certain of their own ability, confident of success. Being so assured, they think that it would be for the benefit of others if they could be persuaded to do things as they themselves do, or as they are certain is right. Even in illness they will direct their attendants. They may be of great value in emergency.
