forming a filter element from natural fibers, the filter element having an element body surrounding a central axis, the element body extending from a first end to a second end along the central axis;

forming an orifice in at least one surface of the filter element, the orifice extending into the element body in a radial direction relative to the central axis;

inserting a capsule into the orifice, the capsule comprising a flavoring agent; and

after inserting the capsule into the orifice, positioning the filter element within an internal elongated cavity of a member body comprising one or more dried leaves, wherein the capsule is contained within the orifice by one or more dried leaves of the member body.
