According to my research, Licorice root is good for cats with allergies, arthritis, etc. as it is a natural cortisone and anti-inflammatory. The sites I visited recommend that the cat be allowed to nibble on a plant, just like with catnip or catgrass. With a cat the age of your's, I would not attempt to dose her without the express instructions of a veterinary professional, expecially since it has cortisone-like properties. The drops must be concentrated and you don't want to overdose your cat.
