BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a medical herb composition and a method for preparing the same and, more particularly, to a medical herb composition for reducing shedding, promoting hair growth and vitality in a mammal, and a method for preparing the same. 
     2. Description of Related Art 
     According to traditional Chinese herb material science theory, it is considered that: the human kidney is the root of innate endowment, and the essence is hair. Therefore the growth and shedding process of human hair reflects the exuberance and debilitation of the essential qi in the kidney. The hair of people whose kidney qi is flourishing is luxuriant and shiny, and the hair of people whose kidney qi is insufficient is easy to fall out, become shrivelled and turn to white. The growth, falling out, glossiness and haggardness of hair are not only respectively related to the exuberance and debilitation of kidney qi, but are also closely related to the exuberance and debilitation of qi and blood of the human body. Due to qi and blood insufficiencies in the body and deficiency of kidney essence, aged people often appear the condition of alopecia, and this is the objective law of birth, growth, robustness and age in the human body. The alopecia of youth not only affects the whole impression, but also may be a signal of kidney deficiency and blood deficiency occurring inside the body. According to traditional Chinese herb material science, the method for curing alopecia mostly adopts enriching yin and tonifying kidney. 
     There are many Chinese herbal materials used for enriching yin and tonifying the kidney. Among them,  Eclipta prostrata, Ligustrum Lucidum, Polygonum multiflorun , etc. are most frequently applied for improving function of hair growth. Although there are old data records of these herbal material used for improving hair growth, there is no valid evidence for supporting the real effect so far. 
     According to the descriptions in ancient medical documents,  Eclipta prostrata  is the dried aerial part of Compositae plant,  Eclipta prostrata  L. It tastes both sweet and sour, and its medicinal property is classified as a little “cold.” In addition, the effect of  Eclipta prostrata  enters the liver and kidney meridian, and function in cooling the blood to stop bleeding, nourishing liver and kidney, clearing heat and detoxifying. The main medical effect of the  Eclipta prostrata  is used for curing teeth loosing, premature whitening of hair, dizziness, tinnitus, waist and knee ache and weakness, yin deficiency and blood-heat, hematemesis, epistaxis, hematuria, blood dysentery, flooding and spotting blood, and traumatic injury bleeding. It is also said that  Eclipta prostrata  for internal use can blacken the beard and hair, and even promote the effect of hair growth occasionally. However, there is no evidence for supporting the mentioned medical effect. 
       Ligustrum Lucidum  is the fruit of common holly which is classified as Oleaceae evergreen large bush, or dried mature fruit of small tree plant  Ligustrum Lucidum  A it. It tastes sweet yet also a little bitter, and its property is neutral and has no toxin. It goes back to liver and kidney meridian in body and tonifies kidney and nourishes yin, emolliates the liver, improves vision, strengthens heart, fortifies lumbar and knee, nourishes, relaxes the bowels, blackens the beard and hair, heavily settles, calms pain, reduces inflammation, releases heat, replenishes yin, tranquilizes, and clears weakness. It is often used for blackening the beard and hair in men, although its effects of hair growth are mentioned occasionally. However, there is no evidence for supporting the effect. 
       Polygonum multiflorun  is dried root and stem of Polygonaceae Polygonum plant  Polygonum multiflorun  Thunb. It tastes sweet yet bitter and astringent, and its property is “warm.” It goes back to meridian of liver, kidney, heart and lung etc, nourishes yin, energizes body, tonifies essence and blood, and tonifies the liver and kidney. It is also used in improving blood deficiency, sallowness, waist and knee ache and weakness, abnormal seminal emission, vaginal discharge, liver-kidney deficiency, head and eyes dizziness, premature whiteness of beard and hair, persistent malaria, ulcer, scrofula, intestinal dryness, constipation, insomnia, impotence, premature ejaculation, tinnitus, uterus bleeding etc. It is said that  Polygonum multiflorun  can blacken the beard and hair, although it is mentioned for its effects on hair growth occasionally. However, there is no evidence for supporting the effect.

     Besides, since it is said that  Eclipta prostrata, Ligustrum Lucidum, Polygonum multiflorun  etc. also have effects of reducing hair shedding, promoting hair growth, and blackening hair, the most frequently applied material,  Eclipta prostrata  is used as a contrast example (please see details in example 1). 
     The dosage of administration is calculated according to body weight. Each human body takes 0.5˜1 g for every 10 Kg weight everyday (taking 1 g/10 Kg for first three months, follow-up taking 0.5 g/10 Kg). The curing effect is determined in three months as a period of treatment, according to individual perception and photo records as the determined standard of curing effect. For obtaining scientific data, the effects classified as 0˜5 scores are shown. The classifying index for scoring includes following four items, i.e. evaluation of exempting alopecia, evaluation of growing hair (newgrown fuzz), evaluation of vitality, and evaluation of skin condition and complexion. 
     [Score Standard] 
     
         
         0 point: no improvement at all 
         1 point: rare improvement, barely detectable 
         2 point: slightly improved 
         3 point: definitely improved 
         4 point: obviously improved 
         5 point: very obviously improved or others can determine differences easily by naked eye 
       
    
     EXAMPLE 1 
     
       Eclipta prostrata  
     
     Six volunteers are tested in the present example. Subjects are given continuous oral administration of scientifically concentrated traditional Chinese herb material powder of  Eclipta prostrata , and statistics are compiled three months later (see details in  FIG. 1 ). The classifying index for scoring includes four items, i.e. evaluation of exempting alopecia, evaluation of growing hair (newgrown fuzz), evaluation of vitality, and evaluation of skin condition and complexion. The score of each item of the test in the present example is 1.0, 0.5, 0.7, and 0.7 point respectively, and the score indicates that the test result falls into the range of “rare improvement, that could be hard to detect”. The medical effects of  Eclipta prostrata  for growing hair and exempting alopecia claimed by people are verified to be not clear in the present example. It is also shown that  Eclipta prostrata  has to cooperate with other medical herb materials to gain more valid curing effects. 
     EXAMPLE 2 
     Prescription A 1   
     Nine volunteers are tested in the present example. Subjects are given continuous oral administration of scientifically concentrated traditional Chinese herb material powder of prescription A 1  (Astragali Radix, Angelicae Radix, and Rehmanniae Radix, as listed in Table 1) and statistics are compiled three months later (see details in  FIG. 2 ). The classifying index for scoring includes four items, i.e. evaluation of exempting alopecia, evaluation of growing hair (newgrown fuzz), evaluation of vitality, and evaluation of skin condition and complexion. The score of each item is 4.1, 2.4, 3.3, and 2.9 points respectively. Among them, the curing effect of exempting alopecia is very excellent, and the curing effect of growing hair (newgrown fuzz), vitality, and skin condition and complexion also meet to the requirement of definite improvement. The curing effect of the medical herb composition of the present invention tested and verified in the present example have curing effect far superior to that of single  Eclipta prostrata.    
     The subject of the present example Mr. Chou, a 43-year-old male, began shedding hair on the calvaria with unknown reason 20 years ago. The boundary line of Mr. Chou&#39;s hair also moved back; the hair on the part of shedding grew thinner and thinner; and the hair started to shed when length reached about 1 to 2 cm. After taking prescription A 1  for one month, Mr. Chou found that the amount of shedding hair had reduced, and his vitality had also improved. After taking prescription A 1  for three months, Mr. Chou found that fuzz on calvaria thickened, and his family members also observed that his hair was clearly growing more. Moreover, the hair on his forehead also began to thicken. After taking the product for four months, the amount of shedding hair continuously reduced; the hair on calvaria and forehead turns thick; and the complexion became much ruddier than it was three months ago. 
     EXAMPLE 3 
     Prescription A 2
