3. Tonifying the kidney to control seminal emission:
For kidney-deficiency loose of seminal gate with sperrnatorrhea, dizziness, tinnitus, lassitude and amnesia, it is used with herbs for benefiting the kidney to astringe essence such as semen euryales, os draconis fossilia ossis mastodi, semen astragali cornplanati, fructus alpiniae oxyphyllae, etc.
Common Uses of Lotus Seed and other Lotus Plant Parts:
Lotus seeds are classified as astringents, being sweet and neutral, and benefiting the spleen, kidney, and heart. The sweet taste and nourishing qualities of the seed are responsible for the benefit to the spleen; this helps stop diarrhea associated with qi deficiency. The astringent quality helps prevent loss of kidney essence, so the seeds are used to treat weak sexual function in men and leukorrhea in women. The seed also has calming properties that alleviate restlessness, palpitations, and insomnia (more so in the whole seed with embryo). The medicinal dosage is 6-15 grams when it is combined with other herbs that have similar applications and double that when used as the main ingredient (the amount in the bean and lotus soup is about 7 grams per serving and in the cream lotus soup and sweet lotus desert about 37-40 grams per serving).
As an example of a therapy for diarrhea, one ounce of lotus seed is soaked in warm water for a few hours, then an adequate amount of rock sugar is added (to taste), and the mixture is simmered until the lotus seeds are well done. To this thick soup a cup of tea-made by steeping 5 g of black tea in boiling water-is added to yield the medicinal food. Traditional herb formulas for diarrhea are described in the next section.
Inside the seed there is a green embryo that is quite bitter; it is usually removed before the seed is provided as a food product. The embryo (lianzixin; heart of the lotus seed), is classified as bitter and cold and benefiting the heart; it dispels pathogenic heat from the heart to treat fidgets and spontaneous bleeding due to heat. The bitter components are isoquinoline alkaloids with sedative and antispasmodic effects. The alkaloids dilate blood vessels and thereby reduce blood pressure. Small amounts of the alkaloids are found in the seeds with embryo removed, and these may contribute an antispasmodic action for the intestines, helping to alleviate diarrhea.
The lotus leaves (heye) are also bitter, but neutral, and are said to benefit the stomach, spleen, and liver. They are used for treatment of summer heat syndrome and dampness accumulation; they also contain the lotus alkaloids with hypotensive effect. Lotus leaf has become popular for lowering blood lipids and treating fatty liver; it is commonly combined with crataegus, which promotes blood circulation and lowers blood fats, for that purpose. Lotus stems (hegeng) are used medicinally in the same way as the leaves for treatment of summer heat and are used also to treat tightness in the chest due to obstruction of qi circulation.
Lotus stamen (lianxu) is sweet, astringent, and neutral, benefiting the heart and kidney; it is mainly used for preventing discharge, such as treatment of leukorrhea or for frequent urination. It contains flavonoids and a small amount of alkaloids. Lotus nodes, the rhizome nodes (oujie), are astringent and neutral, benefiting the liver, lung, and stomach. They are mostly used to control bleeding. All the parts of the lotus have some antihemorrhagic effect, but the rhizome nodes are relied upon for that purpose specifically. The active component for reducing bleeding is not yet established, though quercetin and other flavonoids may play a role by improving capillary wall strength. By charcoaling the lotus plant parts, as is sometimes done, a hemostatic effect is assured, as charcoal itself has this effect (it promotes blood coagulation).
