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.

Description of the plant:
Habitat of the herb:Slopes, margins of mixed forests and dense forests at elevations of 700 - 2500, occasionally to 3500 metres.
Edible parts of Cornus chinensis:The following notes refer to the closely related species C. officinalis, they probably also apply to this species:- Fruit - raw or cooked. The fully ripe fruit is quite pleasant but slightly astringent. It is about 1.5cm long. The fruit contains about 8.6% sugars, 2.9% malic acid, 0.74% ash.
Propagation of the herb:Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed. The seed must be separated from the fruit flesh since this contains germination inhibitors. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year. Scarification may also help as may a period of warm stratification before the cold stratification. Germination, especially of stored seed, can be very slow, taking 18 months or more. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage. Layering of new growth in June/July. Takes 9 months.
