Abstract
Higher concentrations of oak bark ash extract, i.e., greater than 20% by weight, are useful for the treatment of skin cancers. Lower concentrations of oak bark extract possess additional therapeutic properties not heretofore recognized. For example, preparations containing 40-80% oak bark extract are useful in the treatment of acute cancerous skin ulcers. In addition, synthetic mixtures containing potassium ions, zinc ions, calcium ions provide many of the same advantageous properties of oak bark extract. The inclusion of rubidium ions and sulfur is also advantageous for some applications.
