Have you tried Rescue Remedy?
From the Kitchen Physician
FLOWER ESSENCES AND REMEDIES are dilute extracts of various flowers. Bach Flower Remedies are the most popular and were developed in England by Dr. Edward Bach, who spent his life researching and developing the thirty-eight remedies that he discovered. These gentle essences work on the emotions of the body, and both animals and people respond well to their use. They can be used to treat various emotional problems as well as to modify behavioral problems. Each of the thirty-eight remedies treats a particular emotional state. For example, an essence called Holly is helpful for treating a parrot that tends to fight with other birds or is aggressive toward people. There are essences that help them to overcome fear or anxiety, to adjust to new circumstances such as moving to a new home, and to accept a new addition to the family. The most well known and useful essence is Rescue Remedy which is a combination of five of the Bach Flower Remedies.
Although flower remedies can help a lot with behavioral problems, such as biting and aggression, it is important to combine the remedies with training and behavior modification. Fear, a common problem in animals, also can be helped by suitable remedies. A combination of Rescue Remedy and the homeopathic remedy Aconite often will help in situations that involve fear, general lack of confidence, and any kind of stress. Parrots that have been rescued or abused often benefit from the use of appropriate flower essences, which can help to restore their confidence and trust in their caretakers and in the world around them.
To misquote Paracelsus, one of the most enlightened medical masters in Western history, "The parrot body is vapor materialized by sunshine, mixed with the life force of the stars." This is perhaps an esoteric way of saying that our birds are more than just a collection of feathers and body tissue. Eastern mystics discovered many millennia ago that matter is nothing more nor less than condensed, highly organized energy, but Western medicine has failed to translate this to health care. We are just beginning to acknowledge that alternative healing methods have a place in the treatment of human and animal problems. After all, what really counts is how well it works, not how well it accords with our preconceived ideas of medicine.
