The invention belongs to the technical field of tobaccos, and particularly relates to a cigarette/cigar filter tip stick prepared from natural materials. The cigarette/cigar filter tip stick is prepared from, by mass, 100-150 parts of active carbon granules, 60-90 parts of plant fibers, 110-140 parts of wheat, 50-80 parts of barley, 30-70 parts of corn, 40-60 parts of buckwheat, 10-40 parts of rice, 5-15 parts of sesame, 5-110 parts of a vegetable adhesive, 5-20 parts of a vegetable preservative, 30-150 parts of a plant fermentation agent and 10-25 parts of water. The problems are solved thatwhen an existing cigarette filter tip burns, a lot of smoke can be generated, and the filter tip is not easily degraded; through the cooperation of the natural materials and the active carbon, the filter tip stick is good in filter effect and high in environmental friendliness, and the cigarette/cigar filter tip stick achieves the effect of reducing the harm of the smoke to the human body.
