Some plants are called herbs. 


Herbs are many kinds of plants. People use them in many ways. 
In science, an herb is a small plant. It does not have a woody stem. These plants die back to the ground each year. Some herbs grow back from seeds. We call these annuals. Others live for many years. We call these perennials. 
Many people use herbs for food. Culinary herbs give flavor to meals. They are not used in large amounts like vegetables. Some herbs are used as spices. Spices often come from seeds or bark. 
Herbs can also help the body. People use them in medicine. Some herbs are used to make tea. You can use dried leaves or flowers. This is called an infusion. 
Some herbs are used for smells. People make creams and lipsticks from them. They also use herbs in many religions. Some people use them for special rituals. Herbs have been useful to humans for a very long time.

The term "herb" carries different meanings depending on whether you are talking to a chef or a scientist. In a general sense, herbs are plants used for their savory or aromatic properties. People use them to flavor food, make medicines, or create fragrances. 
In the field of botany, the definition is much stricter. A botanical herb is a plant that does not produce a woody stem. The adjective "herbaceous" describes parts of a plant that are green and soft in texture. These plants are often small and seed-bearing. Most importantly, all their parts above the ground die back to the soil at the end of the growing season. This is very different from trees or shrubs. Trees can grow over ten meters tall and have woody stems. Shrubs are smaller, usually staying under ten meters, but they also possess woody structures. 
Herbs can be categorized by their life cycles. Annuals are plants that grow, flower, and die within a single growing season. They must grow from seeds the following year. Biennials have a two-year life cycle. Perennials are plants that live for many years. Even within these categories, uses vary. Some plants, like rosemary or sage, are used as culinary herbs but are not botanical herbs because they have woody stems. Others, like dill, can be used as both an herb and a spice depending on whether you use the weed or the seed. 
Humans have studied and used herbs for thousands of years. The ancient Greek philosopher Theophrastus was one of the first to divide plants into trees, shrubs, and herbs. In the Middle Ages, people believed in humoral theory. They thought certain foods could change a person's internal temperaments. For example, a 14th-century recipe for "green sauce" used parsley and sage to help settle a person's temperament. 
Medicinal herbalism has deep roots in many global cultures. As far back as 5000 BCE, the Sumerians used herbs for healing. In China, traditional herbal medicine has been practiced since at least the first century CE. In India, the Ayurveda system is built entirely around herbal use. Some plants contain phytochemicals, which are chemical compounds that affect the body. While some herbs like St. John's-wort can help with stress, others can be toxic in large amounts. 
Herbs also play a major role in spiritual and religious life. Many religions use specific plants in their rituals. For example, myrrh and frankincense are used in Hellenistic religion. In Hinduism, cannabis is used, and in Wicca, white sage is significant. Some cultures, like the Cherokee, use white sage and cedar for spiritual cleansing. Beyond religion, herbs are used in the beauty industry. They are found in cosmetics like face creams, deodorants, and sunscreens. To make herbal lipsticks, scientists sometimes use partition chromatography. This is a process that separates natural oils from a watery solution using pressure.
Finally, herbs connect to many different biological systems. In the wild, some plants are used as "strewing herbs." These are scattered on floors to provide a sweet smell or to act as disinfectants. Some even act as insecticides to repel pests like fleas. From the tiny mosses and algae to the large trees used in herbalism, these plants are woven into the fabric of human survival. They provide us with food, health, and even the scents we use every day.
