Mallow Drug Interactions, Uses, Effectiveness, Safety & More

Mallow usually refers to Malva sylvestris, a flowering plant in the mallow family. It grows widely across Europe, Asia, and parts of North Africa, and is often found as a roadside or garden plant with pinkish-purple flowers.

People have used the leaves and flowers of mallow for centuries in traditional and folk medicine. The plant is rich in a slippery, gel-like substance called mucilage. This soothing quality is why mallow is most often taken as a tea or gargle for sore throats and coughs, or applied to the skin for minor irritation.

Mallow is closely related to marshmallow (Althaea officinalis), another mucilage-rich herb, and the two are sometimes used in similar ways.

The main active components in mallow are believed to be mucilage (soothing polysaccharides) and plant compounds such as flavonoids and anthocyanins. The mucilage forms a slippery, protective film when mixed with water.

This film is thought to coat irritated tissues in the throat, mouth, or digestive tract, which may explain the soothing effect people report. Laboratory studies suggest mallow extracts may have mild antioxidant and anti-inflammatory activity.

Keep in mind that most of these effects come from laboratory or animal research. How well they translate to real benefits in people is not well established.

Mallow is generally considered low-risk when used in normal food or tea amounts for short periods. However, because there is little formal safety research, caution is wise, especially with concentrated extracts.

Pregnancy: There is not enough reliable safety information, so mallow should be avoided during pregnancy.

Breastfeeding: Safety while breastfeeding is unknown, so it is best avoided unless your doctor advises otherwise.

People with allergies to plants in the mallow family should avoid it. If you have a chronic health condition or take prescription medicines, talk with your pharmacist or doctor before using mallow. Always buy from a reputable source, since herbal products are not tightly regulated.

Mallow is usually well tolerated. When side effects occur, they are typically mild and may include:

• Stomach upset or loose stools, especially in larger amounts
• Allergic reactions in people sensitive to mallow-family plants

Serious side effects appear to be rare, but because research is limited, the full safety profile is not fully known. Stop using mallow and seek medical care if you develop a rash, swelling, or trouble breathing.

There is no standardized, well-established dose for mallow. Traditional use often involves a tea made from a small amount of dried leaves or flowers steeped in hot water.

Because products vary widely in strength and form (tea, capsule, or liquid extract), the best approach is to follow the directions on the product label. Do not exceed the recommended amount.

If you are unsure how much to take or how long to use it, check with your pharmacist or doctor first.
