Location
Venture to the Brunet Meadow and, between the large Chestnut and the road dividing off the Brunet Pavilion, look for a slender tree with weeping branches and adorned with ripe, red, fruit. On first glance a weeping crab apple maybe what springs to mind.
From the temperate regions of the Northern Hemisphere, the genus, Cornus, comprises 45 species. These are commonly referred to as Dogwoods or Cornels. Many of the dogwoods, found elsewhere in the Garden, are grown for their numerous pink or white, flower-like bracts and for their stunning autumn colour.
The Sour Mountain Date does produce attractive bright yellow flowers on bare wood and autumn toned leaves. However, its greatest charm is the fruit. Reputed to have aided the longevity and exceptional health of Emperor Qian Long of the Manchu Dynasty (1644–1911), these fruits have been much celebrated in Chinese herbal medicine. Content in just viewing the beauty this small tree exhibits, it makes quite a tonic for one’s spirits.

Product name : Cornelian Cherry Fruit Extract(dogwood fruit extract; cornus officinalis extract).
Ingredient : Ursolic cid 10%-50%.
Function : replenish the liver and kidney, restrain seminal discharge and relieve collapse
It has been used for at least 2,000 years in Chinese herbal medicine. It is a herb that "stabilizes and binds" and is used principally to reduce heavy menstrual bleeding and unusually active secretions including copious sweating, excessive urine, spermatorrhoea and premature ejaculation.
Like all herbs that suppress bodily fluids (even excessive ones), it will simply prolong or lead to a worsening of symptoms if it is used without tonic or detoxifying herbs.
It is, therefore, normally used in combination with herbs such as Rehmannia glutinosa and is an ingredient of the "Pill of eight ingredients" which is used in China to "warm up and invigorate the yang of the loins".
The fruit is antibacterial, antifungal, hypotensive, antitumor, astringent, diuretic, hepatic and tonic.
The fruit, without the seed, is decocted for the treatment of arthritis, fever and a wide range of other ailments.
 It is used in the treatment of senile lumbago, diabetes, cystitis, tinnitus etc.
The fruit has an antibacterial action, inhibiting the growth of Bacillus dysenteriae and Staphylococcus.
The fruit is harvested when fully ripe and is dried for later use.
The stem bark is astringent, antimalarial and tonic.
The plant is antibacterial, diuretic, hypotensive and a urinary antiseptic.
