Herbs do not heal, they feed. Herbs do not force the body to maintain and repair itself. They simply support the body in these natural functions. Herbs do not address disease. For instance, you might eat carrots for good eyesight and broccoli for immune supporting antioxidants.
Herbs always work, they work because they are only feeding the body.
Also, some people have poor digestive systems and may not be absorbing the nutrients completely. Joy of life is the foundation of natural health, not fear of death. Seek a health professional that helps you further your choice and rights. Modern farming practices and food processing have rendered our food supply deficient and unbalanced. Our bodies take in too much of some things, not enough of others, and some things that should never be consumed.
