Isolation or extraction methods of medicinal preparations of undetermined<br />
constitution containing material from algae, lichens, fungi or plants, or derivatives<br />
thereof, e.g. traditional herbal medicine<br />
NOTE<br />
-<br />
If the isolation or extraction method is considered relevant, at least one symbol of<br />
<strong>A61K</strong> 36/30 should always be given. The method can be further characterized by<br />
additional <strong>A61K</strong> 36/10 and/or <strong>A61K</strong> 36/50 symbols. The last place priority rule does<br />
not apply in this part of the scheme<br />

stress<br />
<strong>A61K</strong> 2236/13 . . involving cleaning, e.g. washing or peeling<br />
<strong>A61K</strong> 2236/15 . . involving mechanical treatment, e.g. chopping up, cutting or grinding<br />
<strong>A61K</strong> 2236/17 . . involving drying, e.g. sun-drying or wilting<br />
<strong>A61K</strong> 2236/19 . . involving fermentation using yeast, bacteria or both ; enzymatic treatment (<br />
