* [[Glycoalkaloids]] : As a treatment for keratoses, glycoalkaloids are thought to work by exploiting structural differences between healthy and sun-damaged skin cells. As skin cells are damaged, the cell walls become more permeable, allowing glycoalkoloids to penetrate into abnormal cells. Once inside the cell walls, glycoalkaloids release enzymes that apparently break down the cells from the inside out.
*[[eggplant]] : A cream formulation containing high concentrations (10%) of a standard mixture of solasodine glycosides (BEC) has been shown to be effective in the treatment of malignant and benign human skin tumors. (see also : [[Glycoalkaloids]])
* [[Radium Weed]] : An active ingredient of E. peplus sap has been identified as ingenol mebutate (PEP005). Studies show that when Ingenol mebutate is applied to the skin it not only kills the cancerous cells but also recruits white blood cells known as neutrophils that appear to reduce the risk of relapse by destroying any residual malignant cells that could allow the tumour to re-grow.
* [[Milk Thistle]] extract, called silibinin, protect against skin cancer-causing ultraviolet-B (UVB) radiation, but it also kills cells that have undergone mutations due to ultraviolet-A (UVA) radiation -- a process that would potentially lead to cancer.
*[[Ginger]] and its constituents have been studied to inhibit Skin Cancer.
* [[Modified Citrus Pectin]] : Several animal studies found that MCP helped reduce the spread of prostate, breast, and skin cancer.
* non-melanoma skin cancers and pre-cancerous lesions treated with diluted [[tea tree oil]] inhibits tumor growth and causes tumor regression.
* [[Mayapple]] extract is used externally to treat all types of external warts and some skin cancers.
* [[Grape seed extract]] shows remarkable protective effects against three major cancers: squamous cell carcinoma and prostate and hematologic malignancies.
*[[Mint]] exhibits the capacity to protect the animals’ lungs, skin and colon against the formation of cancer.
