Homeopathy is safe because remedies are diluted so that extreme reactions will not happen. They are specially treated, so they are powerful, but, they only affect you if they fit your you and your stress reactions some significant ways.
Your perceptions are most important
Like the elephant's ears, we all have a sensory system that tells us when we are in danger or are uncomfortable. Homeopaths are trained to carefully consider your description of what you sense about your problems. Those are your experiences and you are the authority on your experiences.
A therapist cannot hope to know all about you. So, they rely on drilling down deep into your description of your perceptions. During an interview, you will learn about yourself in ways that may surprise you, but ultimately you are in control and you guide the therapist into a limited but deep understanding of your sensitivities and perceptions.
After the right medicine has been selected for your use, the best way to use the medicine needs to be explored. There are more effective ways to use remedies and you should rely on your therapist to guide you.
The wrong remedy will not affect you at all.
Immune system protection
The right medicine is protection against the effects of stress. For example, if you are stressed, your immune system will not perform well. Your immune system is your natural defense system. The correct homeopathic remedy will stimulate your defense system. Some patients describe a weak defense system others describe an overly defensive immune system. If you are too defensive, you will have allergies and the right remedy will calm your defenses.
For plants, pets and infants, we looks for signs of their sensory perception by observing behavior. Homeopathic treatment is also designed to respond to those non-verbal signals.
