We have "Fungus Link" by Doug Kaufman, which explains the role of fungus and many diseases.

I have the "More Excellent Way" by Henry Wright, he is a pastor who studied medicine. This book shows and reveals spiritual roots of disease.

I also have Don Colbert's "The Bible Cure for Candida & Yeast Infections." He is a spirit-filled medical doctor who has healed cancer. We have healing through deliverance. Many people have spiritual roots to their disease. Diseases which cannot be dealt with other than by the power of God.
