**9. Conclusions**

This chapter provides an overview of the characteristics of the areca nut and its impact on human health, especially in an anticancer and immunomodulatory effect. Areca nuts from Aceh, Indonesia, contain flavonoids, phenolics, catechin, quercetin, and a small percentage of tannins which contribute to antioxidant activity. The areca nut has anticancer potential activity so it can be used in combination with chemotherapeutic agents to enhance the effect at lower doses and thus minimize chemotherapy-induced toxicity. Areca nuts also show immunomodulatory activity which can increase the body's immune system.
