Throughout history, the spice turmeric has been a favored seasoning for curries and other Indian dishes. Its pungent flavor is also known to offer medicinal qualities—turmeric has been used for centuries to treat osteoarthritis and other illnesses because its active ingredient, curcumin, can inhibit inflammation.
A new study led by a research team at Ludwig-Maximilians-Universität, in Munich, Germany, has shown that turmeric can also restrict the formation of metastases and help keep prostate cancer in check. The researchers discovered that curcumin decreases the expression of two pro-inflammatory proteins associated with tumor cells and noted that both prostate and breast cancer are linked to inflammation. The study further noted that curcumin is, in principle, suitable for both prophylactic use (primary prevention) and for the suppression of metastases in cases where an established tumor is already present (secondary prevention).
