Hu Zhang: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Hu zhang (Polygonum cuspidatum) is a plant native to Asia. The root is commonly used as part of traditional medicine in countries throughout Asia.

Hu zhang contains chemicals that might reduce symptoms of allergies. It also contains chemicals that might have anti-inflammatory and antioxidant effects.

People use hu zhang for hay fever, diabetes, gout, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.

Uses & Effectiveness

We currently have no information for Hu Zhang overview.

Side Effects

When taken by mouth: There isn't enough reliable information to know if hu zhang is safe or what the side effects might be.

Special Precautions and Warnings

When taken by mouth: There isn't enough reliable information to know if hu zhang is safe or what the side effects might be.

Pregnancy and breast-feeding: There isn't enough reliable information to know if hu zhang is safe to use when pregnant or breast feeding. Stay on the safe side and avoid use.

Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Hu zhang might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use hu zhang until more is known.

Surgery: Hu zhang contains resveratrol. Resveratrol is a chemical that might slow blood clotting. Hu zhang might increase the risk of bleeding during and after surgery. Stop using hu zhang at least 2 weeks before a scheduled surgery.

Interactions

Moderate Interaction

Be cautious with this combination

Medications changed by the liver (Cytochrome P450 1A1 (CYP1A1) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 1A2 (CYP1A2) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 1B1 (CYP1B1) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 2C19 (CYP2C19) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications changed by the liver (Cytochrome P450 2E1 (CYP2E1) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Estrogens interacts with Hu Zhang
Hu zhang seems to have some of the same effects as estrogen. Taking hu zhang along with estrogens might decrease the effects of estrogens.
Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates) interacts with Hu Zhang
Some medications are changed and broken down by the liver. Hu zhang might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs) interacts with Hu Zhang
Hu zhang might slow blood clotting. Taking hu zhang along with medications that also slow blood clotting might increase the risk of bruising and bleeding.

Minor Interaction

Be watchful with this combination

Carbamazepine (Tegretol) interacts with Hu Zhang
Hu zhang might slow down how quickly the body breaks down carbamazepine. This might increase the amount of carbamazepine in the body and increase the risk of side effects. If you take carbamazepine, talk to your healthcare provider before taking hu zhang.

Dosing

There isn't enough reliable information to know what an appropriate dose of hu zhang might be. 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 a healthcare professional before using.
