How It Works

Hollyhock is rich in phenolic and polyphenolic compounds, which have antimicrobial activity that can help the body to resist infections. Extracts of hollyhock leaves and flowers have been found to be effective against Staphylococcus aureus, Salmonella typhy, Escherichia coli, and Streptococcus pyogenes, among other bacteria.1

In addition, a chemical called dihydroflavonol - also present in the flower - is thought to be able to decrease glucose and triglycerides levels in humans. This reduction of sugars in the body may help those at risk of diabetes to avert the condition.2

Tests have also been carried out in order to understand the effect hollyhock can have on muscles during an asthma attack. Although the mechanisms are yet to be fully understood, it is thought that its anticholinergic compounds successfully block the impulses that go through the parasympathetic nerves, helping regulate the movement of the respiratory tract muscles and reducing the spasms that inhibit breathing.3

The extract of hollyhock roots has been shown to reduce calcium oxalate deposits in the kidneys.4

Antispasmodic properties can be found in herbs like hepatica and linden, whereas cinnamon and yacon provide hypoglycemic benefits.

Plants should be thoroughly washed and sanitized before consumption, particularly if a synthetic fertilizer has been used during growth, as these can be harmful to the human body.

    Hollyhock, or Alcea rosea, is part of the Malvaceae or mallow family, which contains 2,300 species spread over 200 genera. This family contains some economically important and well-known herbs, including hibiscus, marsh mallow, mallow, cola nut, and cacao.

    An alternative name for the genus Alcea is Althaea, derived from the Greek word althein, which means to heal. This is indicative of the plant's many medicinal properties.

    The genus Alcea consists of two species, Alcea rosea and Alcea pallida. Both of these are a popular garden flower. Within the Malvaceae family are three species of marshmallow flowers: palm-leaf marshmallow (Althaea cannabina), hairy marshmallow (Althaea hirsuta), and common marshmallow (Althaea officinalis). The last of these was the original ingredient for production of confectioner's marshmallows.

Historical Information

In 17th century Japan, the founder of the Tokugawa shogunate - the last feudal Japanese military government - insisted on using his own hollyhock emblem instead of the traditional imperial emblem of the chrysanthemum to reiterate his opposition to the political power of the Emperor.

It is evident that the plant was introduced to Europe before this time, however, as it can be seen in many 15th century German paintings. By the 18th century, in Germany, hollyhock had become so popular that the poet Goethe had cultivated a vast amount, and he even threw tea parties in its honor.

Economic Data

Hollyhock can be grown in most countries; therefore it is not necessary to import the leaves and flowers for general consumption. Although it is not as commercially significant as other medicinal herbs, hollyhock is being cultivated in vast quantities in the Balkans for the pharmaceutical industry.

Popular Beliefs

In Kyoto, Japan, every year in May there is a large and important festival called the aoi matsuri. This translates to hollyhock festival. At the event, hollyhock leaves are used as the main decoration, as they are said to protect against storms and evil. This celebration has taken place annually since the 6th century.
