Siberian cocklebur is a spring weed that grows in parts of Asia, Europe, and North America. The plant invades farmlands and can be poisonous to domestic animals and humans.
People take Siberian cocklebur by mouth for chronic bronchitis, common cold, constipation, sinus infection, stuffy nose, itching, hives, a condition affecting the joints called rheumatoid arthritis, diabetes, headache, tuberculosis, and kidney disease.
How does it work?
Siberian cocklebur contains many different chemicals. Atractyloside and carboxyatractyloside, which are found in the seed, can be poisonous. In addition to the potential toxic effects of Siberian cocklebur, it might also have anti-arthritis, antibacterial, cancer-protecting, antidiabetes, anti-inflammatory, liver-protecting, and immune system-boosting effects.
Insufficient Evidence to Rate Effectiveness for...
- Chronic bronchitis.
- Common cold.
- Sinus infection.
- Stuffy nose.
- A condition affecting the joints called rheumatoid arthritis.
- Kidney disease.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Children: Siberian cocklebur is LIKELY UNSAFE when the seeds and seedlings are taken by mouth. Deaths have been reported. It is POSSIBLY UNSAFE when the Siberian fruit is taken by mouth. There has been a report of a 20-month old child dying after taking Siberian cocklebur fruit by mouth for 2 months.
The appropriate dose of Siberian cocklebur depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for Siberian cocklebur (in children/in adults). Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
