It is well known that depression is caused (at least in part) from nutritional deficiencies. Urine therapy is perfect for fixing mineral and electrolyte imbalances. Most people believe urine is a waste product. This is incorrect. The body can only process a certain amount of vitamins and minerals at any one time. The test is lost through urine. This makes urine very high in nutrients. Why waste it? Make sure you haven't eaten or drunk anything for at least 2 hours before you ingest urine to make sure you body is ready to accept the nutrients. Try not to mix it with other liquids (eg juice) and the body may absorb those vitamins instead. Secondly I would recommend a remedy that can be used in conjunction with urine therapy.
Energy fields emitted by crystals can help balance weak chakras. (another proven cause of depression simply google it and you'll find plenty of evidence). Simply hold the crystal to your forehead (I use tape. The longer it stays there the better) and within a week you should start to feel better. Which crystal you use may depend on your zodiac simply research which crystals are best for you or you may want to use your birthstone (also good). Let us know if you try either or both of these suggestions and if they worked for you!
