Wasabi is a crop that is native to Japan. It is now grown in other countries, including Taiwan and New Zealand. Wasabi is mainly grown for its roots. The roots are used to prepare sauces and condiments that have a strong and spicy flavor.
Wasabi is used in food as a strong spice.
How does it work?
Wasabi seems to have antibacterial, anti-cancer and anti-inflammatory effects. It also seems to slow blood clotting and stimulate bone growth.
Insufficient Evidence to Rate Effectiveness for...
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).
Surgery: Wasabi might slow blood clotting. In theory, wasabi might cause too much bleeding during surgery. Stop taking wasabi as a medicine at least 2 weeks before surgery.
Medications that slow blood clotting (Anticoagulant/Antiplatelet drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Wasabi might slow blood clotting. In theory, taking wasabi along with medications that also slow clotting might increase the chances of bruising and bleeding.
The appropriate dose of wasabi 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 wasabi (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.
