Herbs at a GlanceNational Center for Complementary and Integrative Health (NCCIH)Interesting info about a bunch of herbs. About 50 on the list. For instance:
Saw Palmetto - The scientific evidence does not support using saw palmetto for any health condition.
Turmeric - High doses or long-term use of turmeric may cause gastrointestinal problems.
Echinacea - Taking echinacea after you catch a cold has not been shown to shorten the time that you’ll be sick.
Garlic - Garlic may be helpful for high blood pressure, but the evidence is weak.
St. John's Wort - It has been clearly shown that St. John’s wort can interact in dangerous, sometimes life-threatening ways with a variety of medicines.
