Abstract (en)
Filter tip for cigarette, containing - in addition to optional tobacco - a dried and chopped vegetable matter such as coltsfoot, hazel leaf and maize. The vegetable matter is preferably expanded and resistance to draught is very great, thereby permitting a high degree of ventilation with improved filter efficiency.
