Basil

Basil is a symbol of fertility and in Italy it is known as the symbol of love because the leaves resemble hearts. Basil deva (vegetable spirit) is a protector of the family, and burning basil oil helps to relieve the negativity of the house.
It creates a sympathetic vibration and is often worn as an assist during clashes with other people. Basil stimulates the conscious mind to invoke happiness. It opens the meridians of the heart and erases the movements of energy between the heart and hands. Basil oil is also associated with clairvoyance, divination and honesty.
