Vanilla refers to plants that emit a unique fragrance. Most of them originate from the Mediterranean coast and are divided into annuals and perennials.

Because vanilla contains alcohols, ketones, lipids, and ether aromatic compounds, the branches and leaves will emit a pleasant aroma, and its roots, stems, leaves, flowers, fruits, and seeds can be used by humans. Vanilla can not only repel mosquitoes and flies, purify the air, and beautify the home, but is also widely used in beauty, bathing, diet, and medical treatment. Representative plants include lavender, rosemary, thyme, patchouli, etc.

Vanilla is native to Mexico and is widely cultivated by Central Americans. In the 16th century, Spanish conquistadors conquered Central America and introduced vanilla and chocolate to Europe at the same time. The English name of vanilla is vanilla. This word originates from the Spanish word "vanilla", which means "little pod" in Spanish.

Although there was a tradition in ancient China of using herbs to make delicacies, the spices used were generally not called "vanilla" later. The "vanilla" used in modern foods "vanilla ice cream" and "vanilla chocolate" is "vanilla beans", which are the seeds of vanilla.

Vanilla has always been generally called "vanilla". Its flowers are fragrant and yellow-green, and the pods of vanilla after flowering and pollination are the important application parts.
