Holly is often thought of as the remedy for anger - but this isn't necessarily the case. In the Bach system, anger is a secondary emotion and we need to look more closely at the cause. Anger based on impatience needs another remedy, for example, as do those angers based on feelings of personal unfairness or impersonal injustice, or where there is a simple loss of control.
Holly is actually the remedy for very negative, aggressive feelings directed at others - feelings such as hatred, suspicion, envy, spite. The basic problem is an absence of love, and this remedy works to encourage our generosity of spirit and an openness towards others.
Suggested for when one needs to control their feeling of hate, envy, and/or jealousy.
