Calendula

Calendula is a genus of about 12-20 species of annual or perennial herbaceous plants in the daisy family Asteraceae, native to the area from Macaronesia east through the Mediterranean region to Iran. Calendula should not be confused with other plants that are also known as marigolds, such as plants of the genus Tagetes, corn marigolds or marsh marigolds. It is also the flower of the month October.

The name Calendula stems from the Latin kalendae, meaning first day of the month, presumably because pot marigolds are in bloom at the start of most months of the year. The common name marigold probably refers to the Virgin Mary, or its old Saxon name 'ymbglidegold', which means 'it turns with the sun'. Marigolds typically bloom quickly (in under two months) in bright yellows, reds, and oranges throughout the summer and well into the fall.

Marigolds are considered by many gardening experts as one of the most versatile flowers to grow in a garden, especially since it is easy to grow.

Marigold petals are considered edible. They are often used to add color to salads, and marigold extract is commonly added to chicken feed to produce darker egg yolks. Their aroma, however, is not sweet, and resembles the smell of hops in beer. The oil from its seed contains calendic acid


USES
Calendula in suspension or in tincture is used topically to treat acne, reducing inflammation, controlling bleeding and soothing irritated tissue.
