Brassica Oleracea Italica Group, Brassica oleracea var. italica, Brocoli, Brócoli, Broccoli Flower, Calabrese, Purple Sprouting Broccoli.<br/><br/>
Overview InformationBroccoli is a vegetable. The parts that grow above the ground are used to make medicine.
Broccoli is used for high cholesterol, fibromyalgia, preventing several types of cancer, and other conditions, there is no strong scientific evidence to support these uses.
How does it work?Chemicals in broccoli might have cancer-preventing and antioxidant effects. Additionally, when broccoli is eaten with a starch, it slows down how quickly sugar from the starch goes into the blood. This is beneficial for people with diabetes.
Uses & Effectiveness
Possibly Effective for
- High cholesterol. Drinking a beverage containing broccoli, cabbage, and fruit twice daily for 12 weeks seems to reduce “bad” low-density lipoprotein (LDL) cholesterol in people with high cholesterol.
Insufficient Evidence for
- Bladder cancer. There is some evidence that eating 1.75 cups of broccoli or cabbage daily might lower the risk of developing bladder cancer by about 30%.
- Breast cancer. There is some evidence that eating broccoli might modestly reduce younger women's risk of getting breast cancer. However, eating broccoli does not seem to help prevent breast cancer in older (postmenopausal) women.
- Colon cancer, rectal cancer. Some research suggests that eating broccoli might help prevent colorectal cancer.
- Fibromyalgia. Early research shows that taking ascorbigen and broccoli powder by mouth might reduce pain and other symptoms in people with fibromyalgia.
- Stomach cancer. Some research has found that eating broccoli might prevent stomach cancer.
- Prostate cancer. Some research has found that eating more broccoli and related vegetables, such as Brussels sprouts, cauliflower, and cabbage, is linked with a reduced risk of prostate cancer. But other research finds no link. There is some evidence that taking a blend of broccoli powder, turmeric powder, pomegranate whole fruit powder, and green tea extract for 6 months can prevent prostate specific antigen (PSA) levels from rising in men with prostate cancer. PSA levels are measured to monitor how well prostate cancer treatment is working. But it's not yet known if this formula, or broccoli alone, reduces the risk of prostate cancer progression or recurrence.
- Other conditions.
Side Effects & SafetyWhen taken by mouth: Broccoli is LIKELY SAFE in the small amounts found in a normal diet. There's not enough information to know if broccoli is safe when taken in larger medicinal amounts.
When applied to the skin: Broccoli can cause an allergic rash in hypersensitive people.
Special Precautions & Warnings:Pregnancy and breast-feeding: Broccoli is LIKELY SAFE for pregnant and breast-feeding women in food amounts. But larger medicinal amounts should be avoided until more is known.
We currently have no information for BROCCOLI Interactions.
The appropriate dose of broccoli 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 broccoli. 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.
