A kind of preparation method of Huangjing chewing pills added with Dendrobium officinale

technical field

The invention relates to the technical field of health food processing, in particular to a preparation method of Polygonum chinensis chewing pills added with Dendrobium officinale.

Background technique

Huangjing, Chinese medicine name. It is the dried rhizomes of Liliaceae Polygonatum kingianum Coll.et Hemsl., Polygonatum sibiricum Red. or Polygonatum cyrtonema Hua. According to different shapes, they are known as "Rhubarb Extract", "Chicken Head Rhizoma Extract" and "Ginger-shaped Rhizoma Extract". It has the effects of tonifying qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. Commonly used for deficiency of spleen and stomach qi, fatigue and fatigue, deficiency of stomach yin, dry mouth and lack of food, dry cough due to lung deficiency, coughing up blood due to labor and cough, lack of essence and blood, soreness and weakness of waist and knees, premature graying of beard and hair, internal heat and quenching thirst.

Dendrobium officinale (scientific name: Dendrobium officinale Kimura et Migo): stems erect, cylindrical, 9-35 cm long, 2-4 mm thick, unbranched, with many nodes; leaves two rows, papery, oblong-lanceolate , margins and midrib often lavender. The racemes often emerge from the upper part of the old stem with deciduous leaves, with 2-3 flowers; flower bracts dry membranous, pale white, ovate, 5-7 mm long, yellow-green sepals and petals, nearly similar, oblong lanceolate, white labial, base with a green or yellow corpus callosum, ovate-lanceolate, slightly shorter than sepals, centrally reflexed. The stamen is yellow-green, about 3 mm long, with a purple spot on both sides of the apex; the cap is white, long ovate-triangular, about 2.3 mm long, the top is nearly acute and 2-lobed. Flowering March-June.

Huang Jing and Dendrobium are both large-scale traditional Chinese medicines in the existing traditional Chinese medicine cultivation. How to deeply develop and improve the market popularity is an urgent problem to be solved at present. Quite a lot of research has focused on the production of Polygonum and Dendrobium into beverages, but in order to ensure the flavor and taste of the beverages, the raw materials in the extraction are wasted to a considerable extent, and the fiber characteristics of Polygonatum and Dendrobium themselves cannot be utilized, resulting in a low degree of resource utilization. .
