licorice
苷 centers on licorice, a sweet plant root used for flavoring and herbal remedies.
苷 is a phono-semantic compound with 艹 (grass/plant) and 甘 (sweet), reflecting its meaning as a sweet plant (licorice). The sound component is likely 甘.
The top 艹 shows it's a plant, and the bottom 甘 means sweet. Together they point to a sweet plant: licorice.
For カン, imagine a can of licorice candy: can -> カン, and the sweet plant 苷 fills the can.
