1. Definition of Calendula Extract

Calendula Extract is a natural substance obtained from the Calendula officinalis flower. This flower, commonly known as marigold, has been used for centuries in various cultures. It is a concentrated form of the active components present in Calendula flowers. These components are extracted through methods like solvent extraction or steam distillation.

2. Types of Calendula Extract

There are different types of Calendula extract based on the extraction method and the intended use:

2.1 Tinctures

Tinctures are alcohol - based extracts. They are often used in herbal medicine. The alcohol helps to dissolve and preserve the active components of the Calendula. Tinctures can be taken orally, usually diluted in water or another liquid, or used topically for certain skin conditions.

2.2 Oil - based Extracts

Oil - based extracts are made by infusing Calendula flowers in oils such as olive oil or almond oil. These extracts are popular in skincare products. They are beneficial for moisturizing the skin and can help soothe irritated skin. The oil - based extract can also be used in haircare products to nourish the scalp and hair.

2.3 Water - based Extracts

Water - based extracts are often used in skincare products. They are made by steeping Calendula flowers in water and then filtering the liquid to obtain the extract. Water - based extracts are gentle on the skin and are suitable for sensitive skin types. They can be used in facial toners, creams, and lotions.

3. History of Calendula

Calendula has a long and rich history:

• The Ancient Greeks used Calendula for its medicinal properties. They recognized its potential in treating various ailments and used it in their traditional medicine.

• The Romans also made use of Calendula. They valued it for its healing abilities and likely used it in similar ways to the Greeks.

• In medieval Europe, Calendula was widely used. It was used in poultices to treat wounds and skin ailments. The flowers were crushed and applied directly to the affected area to promote healing and reduce inflammation.

• Indians also have a long history of using Calendula. In Ayurvedic medicine, it may have been used for its various therapeutic effects.

• It was also used in cooking in some regions. The flowers were added to dishes for their color, flavor, and potentially their health - promoting properties.

4. Nutritional Value of Calendula Extract

Calendula extract contains several important components that contribute to its nutritional value:

4.1 Flavonoids

Flavonoids are antioxidants that play a crucial role in protecting the body from free radical damage. Free radicals are unstable molecules that can cause damage to cells and contribute to various diseases. Flavonoids in Calendula extract help to neutralize these free radicals, thereby reducing the risk of oxidative stress - related conditions such as heart disease, cancer, and aging - related skin problems.

4.2 Triterpenoids

Triterpenoids have anti - inflammatory properties which can be highly beneficial for skin health. Inflammation is a natural response of the body to injury or infection, but chronic inflammation can lead to skin problems such as acne, eczema, and psoriasis. The triterpenoids in Calendula extract can help to reduce inflammation in the skin, soothe irritation, and promote the healing of skin lesions.

4.3 Carotenoids

The carotenoids give the extract its characteristic color and also contribute to antioxidant activity. They are pigments that are also found in other colorful fruits and vegetables such as carrots and tomatoes. Carotenoids in Calendula extract help to protect the skin from UV damage and can also improve the overall appearance of the skin by giving it a healthy glow.
