Feedback:
Conflicting research both supports and disputes ginkgo's ability to enhance memory. Medical studies in both the United States and England have not demonstrated increases in mental function. Despite this research, the "brain herb" is still taken by healthy adults hoping to retain their current memory and cognitive function. The recommended dose is 40 mg standardized extract ginkgo three times daily. The effects of ginkgo may not be evident until after 4 to 24 weeks of treatment. The most common adverse reactions include mild GI discomfort, headache, and rash. Excessively large doses have been reported to cause diarrhea, nausea, vomiting, and restlessness.
