Hollyhock: A Versatile Supplement with Medicinal Properties

Hollyhock (Alcea rosea), a tall, showy plant native to Asia and parts of Europe, has been used for centuries in traditional medicine. Its leaves, flowers, and roots hold an array of medicinal properties, making it a valuable addition to natural health regimens. This comprehensive article explores the diverse uses, potential side effects, precautions, dosing, and scientific evidence supporting the use of hollyhock as a supplement.

Medicinal Uses of Hollyhock

1. Respiratory Health

Hollyhock has long been employed as a traditional remedy for respiratory ailments. Its mucilaginous properties help soothe irritated mucous membranes in the throat and lungs, providing relief from coughs, bronchitis, and asthma. Additionally, hollyhock contains compounds that exhibit anti-inflammatory and expectorant effects, further aiding in the clearance of mucus and the reduction of inflammation.

2. Digestive Health

The mucilaginous nature of hollyhock also benefits digestive health. It acts as a demulcent, forming a protective layer over the lining of the digestive tract. This can alleviate symptoms of gastritis, ulcers, and inflammatory bowel disorders by reducing irritation and inflammation. Furthermore, hollyhock contains compounds that promote gastric juice secretion, aiding in digestion and nutrient absorption.

3. Skin Health

Hollyhock’s anti-inflammatory and antibacterial properties make it beneficial for skin conditions. Its leaves can be applied topically as a compress or poultice to soothe skin irritation, reduce inflammation, and promote healing in cases of eczema, psoriasis, and wounds. Additionally, hollyhock root powder can be added to baths to alleviate skin dryness and irritation.

4. Urinary Health

Traditional medicine has utilized hollyhock for urinary tract health. The leaves have diuretic properties, increasing urine output and potentially aiding in the elimination of toxins and the prevention of urinary tract infections. However, it’s important to note that excessive diuresis can lead to electrolyte imbalances.

5. Anti-inflammatory Properties

Hollyhock contains compounds that possess anti-inflammatory effects. It has been traditionally used to reduce joint pain and stiffness associated with conditions like arthritis and gout. The anti-inflammatory properties may also benefit other inflammatory conditions, such as tendinitis and bursitis.

6. Other Uses

Beyond the aforementioned uses, hollyhock has been employed in traditional medicine for a variety of other purposes, including:

  • Digestive disorders: Nausea, vomiting, and diarrhea
  • Reproductive health: Menstrual irregularities and infertility
  • Hair growth: Promoting hair growth and preventing hair loss
  • Circulatory health: Improving blood circulation and reducing varicose veins

Side Effects and Precautions

While hollyhock is generally considered safe when used appropriately, certain side effects and precautions should be considered:

Side Effects

  • Gastrointestinal upset: Excessive consumption of hollyhock may cause stomach upset, including nausea, vomiting, and diarrhea.
  • Allergic reactions: Some individuals may experience allergic reactions to hollyhock, ranging from mild skin irritation to more severe reactions such as anaphylaxis.
  • Diuretic effects: Hollyhock’s diuretic properties can lead to electrolyte imbalances, especially with prolonged or excessive use.


  • Pregnancy and breastfeeding: The safety of hollyhock during pregnancy and breastfeeding has not been established. Avoid use during these periods unless under the guidance of a healthcare professional.
  • Underlying health conditions: Individuals with certain underlying health conditions, such as severe kidney disease or electrolyte imbalances, should consult a healthcare professional before using hollyhock.
  • Drug interactions: Hollyhock may interact with certain medications, including diuretics and anticoagulants. Inform your healthcare provider about all medications you are taking before using hollyhock.
  • Dosage: Always follow the recommended dosage instructions on the supplement label or as directed by a healthcare professional. Excessive doses may increase the risk of side effects.

Dosing and Administration

The recommended dosage of hollyhock supplements varies depending on the desired use and the form of the supplement.

  • Leaf or flower tea: Steep 1-2 teaspoons of dried hollyhock leaves or flowers in a cup of hot water for 10-15 minutes. Drink 2-3 cups daily.
  • Tincture: 1-2 mL, 1-3 times daily
  • Capsules: 250-500 mg, 1-3 times daily
  • Topical use: Apply a compress soaked in hollyhock leaf or flower tea to the affected area several times daily.

Scientific Evidence

While traditional medicine has long utilized hollyhock, scientific research into its medicinal properties is still in its early stages. Some studies have provided evidence supporting the traditional uses of hollyhock:

  • A study published in the “Journal of Ethnopharmacology” found that hollyhock leaf extract had anti-inflammatory and analgesic effects in animal models.
  • A study in the “Journal of Agricultural and Food Chemistry” reported that hollyhock flower extract exhibited antioxidant and antibacterial properties.
  • A clinical trial published in the “European Journal of Integrative Medicine” suggested that hollyhock extract improved respiratory function in patients with chronic obstructive pulmonary disease (COPD).

However, it’s important to note that more research is needed to fully understand the effectiveness and safety of hollyhock supplements.


Hollyhock is a versatile supplement with a long history of medicinal use. Its mucilaginous, anti-inflammatory, and antibacterial properties make it a potential remedy for various health conditions, from respiratory and digestive issues to skin and urinary problems. However, it’s essential to use hollyhock supplements with caution, considering potential side effects and interactions, and to seek the guidance of a healthcare professional when necessary. As scientific research continues to explore the therapeutic potential of hollyhock, it may become an even more valuable addition to natural health regimens.
