It's essential to note that scientific research on calamus root is limited, and some of its traditional uses may not be supported by modern evidence. 

Additionally, calamus root contains beta-asarone, a compound that has been linked to potential carcinogenic effects in animal studies. 

It's crucial to consult with a healthcare professional before using calamus root, especially if you are pregnant, nursing, or have a pre-existing medical condition.
