Turmeric powder is acquired from the rhizome of the turmeric plant which is found throughout tropical Asia. The powder is generally used as a spice for cooking or rituals. Twenty samples of turmeric with various orange or yellow hues were purchased from stores in the Detroit Metropolitan area. The locations of where the samples were grown were far more widespread. The samples were analyzed with a handheld X-ray fluorescence (XRF) analyzer using the soil fundamental parameters calibration method that reports results for 37 metals. The concentrations of the metals present in each of the samples were investigated. The most common metals found in some of the samples were potassium, calcium, titanium, iron, manganese, and zinc.
