Among the methods used for identification of function group which acted in the human body, the method of electrochemical analysis using cyclic voltammetry was used to determine the effectiveness of cardamom by the oxidation-reduction reaction in the blood medium. Results showed that the cardamom compound presented peaks of oxidation-reduction in the blood serum medium of 0.8 and -0.65 V, respectively. The oxidation peak disappeared in alkaline pH; hence, the cardamom acted as anti-oxidative compound in alkaline medium and with ascorbic acid. But the oxidation peak was enhanced in acidic pH. Other electrochemical parameters of cardamom in blood serum medium were determined, including studies on different scan rates, reliability and stability. Keywords: Cyclic voltammetry; Cardamom oil; Ascorbic acid; Redox reaction; Blood serum Introduction As in the study of the electrochemical analysis of pharmaceutical compounds, researchers have been presently studying medicinal herbs and their effects on the composition of blood by oxidation-reduction reactions [1-6]. Cardamom is an herb, whose seeds and oils from the seeds are used in the manufacture of the drug as shown in the chemical composition in Fig. 1. Cardamom is used for digestive problems including heartburn, intestinal cramps, irritable bowel syndrome, diarrhea, constipation, complaints of liver and gallbladder, and loss of appetite. It is also used to treat colds, other infections, cough, bronchitis, stomatitis, urinary tract problems, epilepsy, headache and high blood pressure [7]. Many biochemical studies have already shown that cardamom has properties that improve health, and this corresponds to the typical properties of agate. Although it is a very promising compound for the feeding field, there is a lack of studies regarding the properties of electrolysis. Cardamom was studied in the voltammetric method. The quantitative limit of the proposed voltmeter methodology is sufficient to analyze the effect of this compound on several phytochemical matrices [8]. Because of its antioxidant and anti-inflammatory quality, spice intake helps to treat diseases., and cardamom is one of these spices. Therefore, The objective of this research was to
