Many herbs and herbal extracts benefit the hair and skin. They were the original natural and organic cosmetics and are used today in the best natural organic cosmetics. Many cosmetic compounders make the mistake of adding various synthetic chemicals to the cosmetic product containing the herbs. This often limits or completely eliminates the good the herb could do for the hair and skin.
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. Herbs generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while spices are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits.
Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp.
The word "herb" is pronounced /hɜːrb/ in Commonwealth English, but /ɜːrb/ is common among North American English speakers and those from other regions where h-dropping occurs. In botany, the noun "herb" refers to a "plant that does not produce a woody stem", and the adjective "herbaceous" means "herb-like", referring to parts of the plant that are green and soft in texture".
"What is a herb?" "The friend of physicians and the praise of cooks."
