much more.
Medical indications of
calendula
Calendula has been used to treat a variety
of skin disorders, ranging from skin ulcerations to eczema. It has
also been used to sooth stomach ulcers and inflammation. Today
Calendula is still used by many for the medicinal and health related
effects it offers. Flavonoids, found in high amounts in calendula,
are thought to account for much of its anti-inflammatory activity as
well as medicinal effects. Triterpene and caretonoids are two other
constituents of calendula that may play an important role in the
herbs medicinal applications.
More recently scientists have
investigated calendula for possible anticancer and antiviral actions
this herb may possess. However, there is not enough evidence at this
time to recommend calendula for any type of treatment related to
these actions.
The following are list of calendula's reported
medicinal applications:
- Wound healing
- Anti-inflammatory

The oil extracted from the calendula herb
serves many purposes. Externally applied to the ear, it has been
reported to alleviate pain and discomfort from an earache. Taken
internally, it may aid in eliminating fever, soothing a festering
ulcer, and relieving discomfort of menstrual cramps. Calendula
provides one of its greatest benefits in relieving eruptive skin
disorders such as shingles, a viral infection. Calendula is
considered by many to be an effective detoxifying herb that can help
