Aerosol-generating substrate

An aerosol-generating article comprising an aerosol-generating substrate, the aerosol-generating substrate formed of a homogenised plant material, comprising:

• between 1 percent by weight and 65 percent by weight of non-tobacco plant particles, on a dry weight basis;
• between 15 percent by weight and 55 percent by weight of aerosol former, on a dry weight basis;
• between 5 percent by weight and 10 percent by weight of cellulose ether, on a dry weight basis;
• and
• between 5 percent by weight and 50 percent by weight of additional cellulose, on a dry weight basis,
• wherein
• the non-tobacco particles comprise star anise particles,
• the non-tobacco plant particles have a D95 value of between 200 microns and 300 microns,
• the additional cellulose is in a form of isolated cellulose and is not derived from the non-tobacco plant particles, and
• a ratio of additional cellulose to cellulose ether on a weight basis in the homogenised plant material is at least 2.
