Alizarin has been used as a staining agent for centuries. Originally alizarin vegetable dye was prepared from the madder plant Rubia tinctorum, but now a synthetic preparation is used that is chemically identical. Madder has been regarded as a mild diuretic.
The Ministry of Health of Russian Federation has approved alizarin as an antiviral preparation for acute and relapsing forms of herpes simplex infection of extragential and genital areas, herpetiform Kaposi's eczema, viral diseases of the oral cavity, herpes zoster and chicken pox in both children and adults.
Currently, there are no well-established therapeutic uses of alizarin. Precautions should be taken while handling this dye due to the lack of safety data.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
The limited available evidence suggests that alizarin may improve various herpes infections. Additional study is needed before a firm recommendation can be made.
*Key to grades:
A: Strong scientific evidence for this use;
B: Good scientific evidence for this use;
C: Unclear scientific evidence for this use;
D: Fair scientific evidence against this use (it may not work);
F: Strong scientific evidence against this use (it likely does not work).
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Anemia, aphrodisiac, blood disorders, bone healing (ectopic), bruises, chicken pox, coloration of articular fluids, diuretic, eczema, edema (swelling), expectorant, flavoring agent, food additive, HIV, jaundice, kidney or bladder stones, leukemia, liver and gallbladder tonic, liver disease, menstrual disorders, paralysis, sciatica (leg pain), skin conditions, spleen disorders, tonic, urinary disorders, urinary tract inflammation, weight gain, wound healing.
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
There is no dose that is proven safe or effective in adults. Madder bark has been prepared by using one teaspoon boiled in a covered container with 3 cups of water for 30 minutes. The liquid is cooled slowly in the closed container and taken cold, 1 to 2 cups per day. For herpes simplex lesions, a 0.2-0.5% ointment has been applied on the skin.
Children (younger than 18 years)
There is no dose that is proven safe or effective in children. Nonetheless, 0.1 gram alizarin tablets three times a day within five days of exposure to chickenpox has been taken by mouth. A 0.2% ointment applied on the skin has also been used.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Patients with a known allergy or hypersensitivity to alizarin, Rubia tinctorum, or other plants from the Rubiaceae family should not take alizarin preparations.
Contact dermatitis from handling stems and roots of Rubia tinctorum has been reported.
Side Effects and Warnings
There are few reports of adverse effects in humans associated with alizarin. However, alizarin may be toxic and should not be handled for long periods of time, rubbed in the eyes, or eaten. Alizarin is potentially carcinogenic (cancer causing) and mutagenic (capable of causing genetic changes). When taken by mouth, madder can cause red-colored urine, salvia, perspiration, and breast milk. There is some concern that madder can stain contact lenses.
Contact dermatitis has been reported in two women, handling wild madder (Rubia peregrina) and madder (Rubia tinctorum).
Other side effects noted include nausea, vomiting, transient weakness, loss of muscle control, sub-acute toxicity, progressive listlessness, hyperirritability, insomnia, and abnormal breathing.
Pregnancy and Breastfeeding
Alizarin is not recommended in pregnant or breastfeeding women. Alizarin dye may cross the placenta. Extracts from madder plant (Rubia tinctorum) are likely unsafe when taken by mouth in pregnant women due to potential menstrual stimulation and genotoxic (damaging to the DNA) effects. The extract can also cause red-colored breast milk.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs
Parts of the chemical structure of alizarin are similar to those in the tetracycline molecule. Therefore, there is a possibility of an additive interaction between alizarin and tetracyclines, such as demeclocycline.
Interactions with Herbs and Dietary Supplements
Currently, there is a lack of available scientific evidence describing herb and supplement interactions with alizarin.

While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.
