Echinacea
One of the best herbs that will help your cats immune system. There are two main species of Echinacea that you should look for. One is the angustifolia and the other is purpurea. Purpurea is the most common for helping to boost your cats immunity. Echinacea also helps to promote antiviral activity in the body, and can help prevent further spreading of bacteria.

Taurine
An essential amino acid that helps regulate the heart, vision, etc. Cats are quite special in their need for taurine because they cannot synthesise it themselves and need to take it in with their diet. If your cats are on a raw food diet, make sure organ meats are present, especially beef heart. Although taurine is present in all raw muscle meat, beef heart has a highest levels of this crucial supplement for your cats.

Catnip
Ah, the king of cat herbs. Catnip is beloved by felines all over the world, and for good reason, it makes them very happy. It’s sort of like an after work cocktail for cats, relieving them of stress and nervousness. Also, if your cat is always scratching, and seems to have itchy skin, a catnip "tea bath" can soothe kitty’s skin. Catnip when sniffed by cats acts as a stimulant, however when ingested catnip will have a calming effect.

Valerian
This pungent herb is best known for helping people to relax and get a good night’s sleep. Not so for Mr. Whiskers. Valerian works as a stimulant on cats; good for transforming lazy, fat cats into exercise machines. Pair this with the fact that cats actually like eating the plant and you’ve got the perfect formula for a healthy, furry feline.

Licorice Root
Not only does it taste good to your cat, licorice root is good for you, too. As a natural cortisone, licorice root can be used to soothe itchy kitties with allergies, endocrine (the endocrine gland affects metabolism, growth and mood) and digestive issues, as well as respiratory problems like colds, since it soothes mucus membranes. Other benefits of the licorice root include blood cleansing and anti-inflammatory properties, so it can be very useful for cats with arthritis.

Goldenseal
No, this isn’t the title of a new James Bond film, but a herb that’s useful for your cat. Goldenseal can be used as a natural disinfectant on wounds, and, in conjunction with saline, may help shrink swollen eyes due to infections and allergies. Of course, with any treatment, herbal or otherwise, make sure you consult your holistic vet prior to treatment or check with your holistic natural health store.
