HERBS AND SPICES

Usually the constituents of medicinal value to humans are secondary metabolites produced by plants for pur- poses other than growth. Advocates for organic garden- ing insist that conditions most closely approximating wild conditions are best for growing herbs, especially medic- inal herbs, because the use of pesticides and herbicides can alter the plants’ constituents, thereby altering their flavors and medicinal attributes.

caraway, dill, and fennel; China produced fennel, garlic, ginger, and cumin; India grew celery seed, fennel, and turmeric; and Croatia produced sage, savory, and rose- mary, to name a few. At that time the herb and spice in- dustry could be divided into three main categories, essential oils, medicinal crops, and culinary herbs and spices (fresh and dried).

Essential Oils

Essential oils are usually found in specialized oil cells or ducts in plants. Oils from aromatic plants are generally volatile, so they are extracted by water or steam distilla- tion. Some volatile and most nonvolatile essential oils are obtained by solvent extraction. The aromatic, resinous product obtained from nonvolatile oils is known as an oleoresin. Oleoresins are concentrated and are widely used in the food industry. For example, pepper oleoresins are used in processed food, while turmeric oleoresin is a common natural coloring agent in food and pharmaceu- ticals. Essential oils are produced and processed all over the world, and France, Brazil, China, Spain, and Mexico are among the largest producers. These oils are often the by-products of another industry, and citrus oils, extracted from the skins of oranges, lemons, and limes, account for a large proportion of the essential oil industry. Pine and cedarwood oils are by-products of the timber industry. Of the herbs and spices planted specifically for oil pro- duction, anise, bergamot, citronella, lemongrass, laven- der, mints, and rosemary are probably the most widely grown. Mints represent the largest essential-oil crop in the United States. Dill is also an important oil crop, used mostly in the manufacture of pickles.

Medicinal Herbs and Spices

It is particularly important that medicinal herbs and spices are grown in ideal rather than marginal conditions so the proportion of medicinal constituents is maximized.

Wild crafting of herbs and spices occurs all over the world. Some herbs, such as echinacea and goldenseal, have become rare in the wild because of overharvesting. Although all herbs can be cultivated, one school of thought says the best medicinal herbs are taken from the wild, so pressure on wild herb populations in all parts of the world continues. Conversely, some cultivated herbs have escaped into the wild, where they have become problem weeds. Harvesting these from the wild helps keep them under control while providing plenty of raw material for processing.

Culinary Herbs

In the past culinary herbs and spices were collected from the wild or grown in gardens among vegetables and flow- ers. By the twenty-first century, although the traditions of collecting flavorings from the wild and growing a few herbs in gardens continued, more people in Western countries demanded interesting and exotic flavors with their foods. This trend produced a proliferation of fresh, processed, frozen, and dried herbs and spices on super- market shelves and a burgeoning industry to support these demands. In these Western countries the processed herb market is mostly supplied by companies that dry, process, package, and transport the produce to market. These companies are usually supplied by contract grow- ers, often from other countries. Many herbs are dried for use as herb teas as well as for flavorings. A smaller but increasing market exists for biodynamically and organi- cally grown herbs, both dried and fresh.

Culinary Spices

Most commercially grown herbs are produced in tem- perate regions, as are the seed spices, such as coriander, dill, cumin, caraway, and fennel. Most spices, however, are indigenous to and are grown commercially in sub- tropical and tropical regions. Each spice is usually grown in just a handful of countries and then exported all over the world. For example, the best cinnamon still comes from its native Sri Lanka; cassia come from China, In- donesia, and Vietnam; cloves come from the Moluccas, Zanzibar, and Madagascar; pepper comes from India, In- donesia, and Malaysia; and ginger comes from Jamaica, Nigeria, and India. The spice saffron is native to more temperate regions, and most of it is grown in and ex- ported from Spain, Kashmir, Greece, and Iran.
