The subject of herbs is harder to define. A botanist from the British Royal Horticultural Society would say that a herb is a plant that dies down to the ground in winter (since that is their Dictionary of Gardening definition). But some sources class plants, like Bay (Laurus nobilis) as evergreen making herb references in this selection closer to the explanation given in the Oxford English Dictionary, where the term herb is "applied to plants of which the leaves or stem and leaves are used for medicine, or for their scent or flavor."
Herbs come in all variety of shape, size and perfume. A particular herb like Sweet Basil (Ocimum basilicum) is not only a delicious cooking herb, but a valuable companion plant for deterring pests from tomato plants and as a fly repellent when planted in pots around the home as well so cross referencing plants for multiple purposes makes perfect sense within the context of a herb thesaurus.
Extracting and standardizing herbal drugs do make the drug in question significantly more expensive than pharmaceutical or synthetic alternatives since many such standardized extracts (such as digoxin/digitoxin from foxglove) are unstable and have a very short "shelf lives." Also, many herbs that contain biologically active compounds contain SEVERAL such compounds, some you might want to be giving to your patient, and some you might not. (For instance, cinchona bark, which was the original source for anti-malarial quinine, also contains some 20 other drugs, including the potent cardiac depressant quinidine. Would you really want to be treating a person for malaria by giving them a "herb" that also contains significant amounts of a cardiac depressant?)
So enjoy herbs for their other properties, they are a wonderful and fragrant addition to any garden, kitchen or bath. But judge carefully when medicinal applications are referenced.
