This book includes descriptions and uses of many natural and complementary protocols for cancer in general and for specific cancers. It also includes information on integrative support during conventional cancer treatment.

Anticancer effects:

  • Promotes apoptosisprogrammed cell death, a normal process of all cells in our bodies. Cancer cells can evade this process and live longer than normal. Therapies that promote apoptosis get cancer cells to die their normal death
  • Promotes autophagyconsumption of the body’s own tissue as a metabolic process occurring in fasting, starvation and certain diseases; cellular self-cleansing  
  • Induces differentiation 
  • Antimutagenic 
  • Stem cell modulation
  • Antiviral regarding cancers linked to viruses 
  • Antimetastatic

Treatment enhancement:

  • Synergistic with carmustine (BCNU)
  • Increase efficacy of radiation therapy by inhibiting TGFbeta

Managing side effects during radiotherapy:

  • Constipation
  • Anorexiaabnormal loss of appetite, often leading to weight loss, nausea, and fatigue associated with intestinal and pelvic radiation
  • Radiation pneumonitis
  • Protection of bowel and bladder from injury during pelvic radiation
  • Proctitis

Managing side effects during chemotherapy

  • Cardiomyopathy from anthracyclines such as Adriamycin/doxorubicin
  • Support mitochondrial recovery

Terrain support:

  • Lower insulin
  • Modulate hormones

Specific cancer protocols:

  • Brain cancer
  • Leukemia, except not with stem cell transplant
  • Liver and gallbladder cancer
  • Multiple myeloma
  • Myelodysplastic syndrome
  • Ovarian cancer
  • Prostate cancer
  • Sarcomas
  • Stomach cancer

Dr. McKinney recommends against using berberine around the time of stem cell transplant due to its suppression of the immune system.
