Las preguntas más frecuentes de los pacientes
The efficacy and role of bran-fried Atractylodes
Raw Atractylodes is warm, dry and pungent, and has strong ability to dry dampness, dispel wind and dispel cold. It is used for rheumatic arthralgia, numbness of the skin, pain in the feet and knees, colds, limb pain, damp-heat fever, joint pain, etc. After bran-frying, the pungent nature is weakened, the dryness is alleviated, the air becomes fragrant, and the effect of strengthening the spleen and stomach is enhanced. It is used for spleen and stomach disharmony, stagnation of phlegm and fluid, fullness in the abdomen, amblyopia, etc.
In clinical Chinese medicine, the “dryness” of Atractylodes is related to its volatile oil. The processing methods such as swill soaking, bran frying, and scorching can reduce the content of volatile oil and play a role in “alleviating dryness”.
Main characteristics of Atractylodes macrocephala and Atractylodes lancea
Atractylodes macrocephala: The rhizome is irregularly nodular or slightly beaded cylindrical, some are curved, usually unbranched, 3~10cm long, 1~2cm in diameter. The surface is yellow-brown to gray-brown, with fine longitudinal grooves, wrinkles and a few residual fibrous roots, and there are often constricted shallow transverse grooves at the nodes. There are round stem scars between the nodes, often with residual stem bases at one end, and occasionally with stem scars. Some white flocculent crystals are precipitated on the surface. The texture is solid, easy to break, the cross section is slightly uneven, off-white or yellow-white, with many orange-yellow or brown-red oil chambers (commonly known as cinnabar spots) scattered, and white fine needle-shaped crystals can be precipitated after being exposed for a while. The cross section does not show blue fluorescence under ultraviolet light (254mm). The aroma is strong, and the taste is slightly sweet, bitter and spicy.
Northern Atractylodes: The rhizomes are mostly lumpy, some are nodular and cylindrical, often curved and with short branches, 4~10cm long and 0.7~4cm in diameter. The surface is black-brown, and the outer skin is yellow-brown when it falls off. Light and loose; the cross section is fibrous, with small yellow-brown oil chambers scattered, and no crystals are precipitated after being placed. The aroma is weak and the taste is bitter and pungent.
The efficacy and role of processed Atractylodes
The raw Atractylodes is warm, dry and pungent, and has strong dampness, wind and cold dissipation. It is used for rheumatic arthralgia, numbness of the skin, pain in the feet and knees, colds, limb pain, damp-heat fever, soreness of the limbs, etc. The processed Atractylodes has the same function as the raw product, but after being soaked in rice water, it can alleviate the dryness and reduce the side effects of pungent, warm and dry, and has the effect of harmonizing the stomach. Chinese medicine clinically believes that the “dryness” of Atractylodes is related to its volatile oil. The processing methods such as soaking in swill, frying with bran, and frying with char can reduce the content of volatile oil and play a role in “relieving dryness”.
The difference between Atractylodes and Atractylodes
Atractylodes is a dehumidifying medicine, which is the dried rhizome of Atractylodes macrocephala or Atractylodes macrocephala of the Asteraceae family. Atractylodes is a tonic medicine, which is the rhizome of Atractylodes macrocephala of the Atractylodes genus of the Asteraceae family. The biggest difference between Atractylodes and Atractylodes is that Atractylodes is better at drying dampness, while Atractylodes is better at strengthening. Atractylodes is pungent and warm in nature, and its nature is relatively dry. Therefore, it is more suitable for patients with dampness that stagnates the spleen, especially when the degree of dampness is relatively severe, and the patient feels fullness in the spleen under the heart, does not want to eat, or vomits immediately after drinking water, and cannot normally transport and transform water and dampness. In addition, it is also more appropriate to use Atractylodes for those who have difficulty in transporting and transforming due to dampness that stagnates the spleen and soil.
The nature and flavor of Atractylodes macrocephala is relatively mild, and its nature is warm, but not dry and strong. Therefore, it is more suitable for patients with spleen deficiency and dampness, poor spleen transportation and transformation function, and water retention. Of course, the common point between Atractylodes macrocephala and Atractylodes macrocephala is that they can remove dampness. For patients with both spleen deficiency and heavy dampness, Atractylodes macrocephala and Atractylodes macrocephala are sometimes used together to form a medicine pair for strengthening the spleen and removing dampness, which is also commonly used in clinical practice.
