4. Botanical Profile of Chamomile

Understanding the botanical characteristics of chamomile is essential for appreciating the origin of its therapeutic properties. In this section, we explore the taxonomy, morphology, and growing conditions of chamomile.

4.1 Taxonomy and Nomenclature

Chamomile belongs to the Asteraceae (sunflower) family. There are two main types of chamomile used for medicinal purposes:

• German Chamomile (Matricaria recutita): Often referred to as “true chamomile,” this species is the most widely used for its high content of essential oils and bioactive compounds.
• Roman Chamomile (Chamaemelum nobile): Although similar in appearance and aroma, Roman chamomile has a slightly different chemical profile and is often used in gentler formulations.

The botanical nomenclature can be confusing because of the many synonyms associated with the plant. For example, Matricaria recutita is also known as Chamomilla recutita or Matricaria chamomilla. Despite these variations, German chamomile remains the most commonly cultivated and studied species due to its potent bioactivity.

4.2 Morphology and Growth Habit

German chamomile is an annual herb that typically grows to a height of 15 to 60 centimeters (6 to 24 inches). Key morphological features include:

• Stem: The stem is slender, erect, and lightly branched.
• Leaves: The leaves are finely divided, feathery, and aromatic. They are usually bipinnate or tripinnate, providing the plant with a delicate, lacy appearance.
• Flowers: The flowers are the most distinctive feature. Each flower head (capitulum) consists of white ray florets surrounding a central disc of tiny yellow florets. These disc florets are the source of the essential oil. In German chamomile, the flower heads are typically small, measuring about 1 centimeter in diameter.
• Scent: When crushed, the leaves and flowers emit a sweet, apple-like fragrance—a quality that has given chamomile its name (derived from the Greek “chamaimēlon,” meaning “earth apple”).

4.3 Distribution and Cultivation

Originally native to southern and eastern Europe, German chamomile now grows in many parts of the world. It thrives in temperate climates and can be found growing wild in fields, along roadsides, and in disturbed soils.
