When choosing plants for the herb garden, cacti and succulents may not be the first thing that comes to mind. However, a number of these species have traditionally been used as herbs. These include the following plants. Some are hardy perennials, while others are winter hardy only in milder areas of the country.

As with a number of other succulents, this should never be taken internally as it can be toxic.
As is the case for most of the sedums, this sedum (Sedum telephium) is considered poisonous when taken internally.

The plant has astringent qualities, which helps wounds to heal quickly.
Native American tribes used the pads of the prickly pears as a dressing for treating burns and scores. First, the spines were removed from the prickly pear pads.

The fresh pads were also made into a poultice to treat arthritis.
Also called reflexed stonecrop, its Latin name is Sedum rupestre. This is a great choice for herb gardens. Unlike some of the other stonecrops, this species is safe to take internally.
