Like I mentioned earlier Ginkgo helps increase the blood flow to the brain, so it comes as no surprise that this herb can aid in cognitive function and memory. It has also been shown to help with symptoms associated with the central nervous system such as tinnitus and vertigo. The brain isn't the only place Ginkgo will increase circulation in fact the whole body from the toes to your head have increased circulation when taking the herb. Most commonly Ginkgo is taken orally via capsules, these can be found for a reasonable price at Walgreens, CVS or the like.
Teas are a great way to get the benefits of sage all you need to do is steep one teaspoon of sage in a cup of water for about 10 minutes. You can also make a pretty awesome sore throat reliever by combining sage and thyme. Take an ounce of both grind them, and cover them with 16 ounces of apple cider vinegar. Be sure to shake it periodically and let it sit for ten days before using.
