Take metformin before eating sugar?

According to the meaning of metformin in traditional Chinese medicine: metformin belongs to fire, and it can damage the liver and kidneys. Wood generates fire. If fire is strong and wood is weak, the child steals the mother's energy. Water and fire are in conflict with each other. If fire is strong, more water is needed to restrain it. And the sky is born with water. Fire overcomes metal, and metal generates water. If metal is damaged, water will be weak, and water is weak and cannot control fire. Long-term use of metformin will inevitably cause liver and kidney damage. The role of the liver and kidneys among the five internal organs is self-evident. The kidneys are the foundation of life

and the liver is the guardian of the whole body.
