What it is
Cornflower is an annual flowering plant in the daisy family (Asteraceae), well known for its vivid blue flowers. The flowers have a history of traditional culinary and herbal use.
Traditional-use context
Traditional references describe mild external and tea uses, but robust clinical evidence for medicinal benefits is limited. This page therefore avoids treatment claims.
Preparation context
Dried petals may be used in culinary or traditional tea blends when the product is sold for that purpose. Use only correctly identified, food- or herb-grade material.
Quality and identification
Choose petals from a reputable source that confirms botanical identity and intended use. Ornamental flowers may have pesticide residues and should not automatically be used as food or medicine.
Safety and precautions
People with allergy to plants in the Asteraceae family should use caution. Seek professional advice during pregnancy, breastfeeding, or if symptoms are being self-treated with herbal products.
Evidence note
Traditional use and modern clinical evidence are not the same. Where an official monograph exists, this page uses it as a primary reference; otherwise claims are deliberately conservative.
