Safety Overview
1.Bitter Chamomile — Plant Snapshot
Bitter Chamomile, known scientifically as Matricaria chamomilla, is a highly valued annual flowering herb. It belongs to the expansive Asteraceae family, which also includes familiar plants such as daisies and sunflowers. This adaptable plant typically reaches a height of 30 to 60 centimeters.
Slender, erect stems that often branch extensively give it its form. Its most iconic features are its charming, solitary daisy-like flower heads. These present bright white ray florets that elegantly surround a prominent, conical yellow central disk of numerous tubular florets.
One critical feature distinguishes it from other chamomile species, particularly Roman Chamomile. This is the distinctly hollow receptacle found beneath the disk florets.
The leaves of Matricaria chamomilla are finely dissected or pinnately divided. This lends them a delicate, feathery, and almost lace-like appearance. When you gently crush these leaves and flowers, they release a characteristic sweet, apple-like fragrance.
This fragrance is the origin of its common name 'German Chamomile' or 'Wild Chamomile.' The root system is generally fibrous and shallow, which perfectly suits its annual growth cycle. Bitter Chamomile is native to various regions of Europe and parts of temperate Asia. It has successfully naturalized across diverse continents, including North America, where it flourishes in a wide array of environments.
You frequently find it in disturbed soils, roadsides, agricultural fields, and meadows. This underscores its remarkable adaptability and resilience. Its widespread distribution and relative ease of cultivation have driven its millennia-long history of use in traditional medicine systems globally, revered for its calming and healing properties.
