As a most important Chinese materia medica, Aconiti Lateralis Radix Praeparata(Fuzi) had been widely used in China for thousands of years. This herbalogical study was systematically performed based on variation characteristics of the naming, habitat, harvesting, processing and properties. The sharp toxicity of Fuzi had been well known since the spring and autumn period in the history, which was much earlier than that its medical properties was understood and applied. Sichuan province was regarded as the geo-authentic region of Fuzi all along, where the best quality goods could be provided for clinic use. The study showed the harvesting time of Fuzi was changing in different periods, and the possible effects were of climate change and artificial planting. The perishable characteris-tics of Fuzi severely limited its storage period; therefore, different kinds of storage methods were effectively used since Tang Dynasty. For thousands of years, Fuzi had been processed with various accessories to reduce toxicity, while simultaneously the study on processing mechanism was on going all the time. Fuzi was widely used in clinical practice to cure Yang depletion syndrome, which was based on its function of enhancing Yang and removing cold. Along with the further study on quality evaluation standard, Fuzi will probably get a much wider range of applications.

Citri Sarcodactylis Fructus is a both medicinal and edible species specified by the China Ministry of Health, with a long history in China. According to the ancient monographs about materia medica, it was found that the records of the Citri Sarcodactylis Fructus on the original plants were confused. This paper reviewed the ancient monographs about materia medica, and made a summarization and textual research on the name, origin, habitat, processing methods, medicinal properties and clinicacy efficacy of Citri Sarcodactylis Fructus based the comprehensive analysis on modern literatures and authoritative books of Chinese herbal medicine. The results indicated that there were many bynames of Citri Sarcodactylis Fructus. Before the Yuan Dynasty, there was a mixed use of Citri Sarcodactylis Fructus and Citri Fructus, which were not distinguished from each other in terms of nature and taste until the Yuan dynasty. Citri Sarcodactylis Fructus was a varietas of Citri Fructus. The main shape of the original plant of Citri Sarcodactylis Fructus is "like a human hand with fingers" as recorded in ancient monographs about materia medica. The main places of origin of Citri Sarcodactylis Fructus were Guangdong, Zhejiang, Fujian, Sichuan, which were relatively stable. There were fewer records about medicinal proces-sing methods of Citri Sarcodactylis Fructus. Only steaming and baking methods were found in ancient monographs about materia medica, and the steaming method could reduce the irritability of Citri Sarcodactylis Fructus. The processing of therapeutic dietary of Citri Sarcodactylis Fructus was widely used in folk, which was represented by Chaozhou Laoxianghuang, a traditional succade made of Citri Sarcodactylis Fructus. According to the 2015 edition of Chinese Pharmacopoeia, Citri Sarcodactylis Fructus had effects in soothing liver and regulating gas, relieving pain in the stomach, eliminating dampness and resolving phlegm, which was basically consistent with the descriptions in ancient monographs about materia medica. This paper defined the original plant of Citri Sarcodactylis Fructus, and sorted out and summarized the processing methods, nature and taste of Citri Sarcodactylis Fructus, so as to provide data support for the standardization of the processing technology and the development and utilization of Citri Sarcodactylis Fructus.

As a representative foreign medicinal material, olibanum(Ruxiang) was imported to China since the Qin and Han Dynasties. Olibanum was first described as a medicinal by the name "Xunluxiang" in Miscellaneous Records of Famous Physicians(Ming Yi Bie Lu). This study investigated historical records on olibanum and conducted the herbalogical study. It was found that olibanum came from the resin mainly obtained from the bark of Pistacia lenticus before the Tang Dynasty. With the prosperity of the Maritime Silk Road, instead, the resin obtained from the bark of Boswellia carterii was mainly used as olibanum. In ancient time, the oleo-gum-resin secreted from the cut bark was collected in spring and summer, and the quality was judged based on transparency and shape. The processing methods of olibanum went through many evolutions, which changed from simple methods such as grinding and frying to complex methods such as levigating and grinding with wine, and now to frying and processing with vinegar. The usage of olibanum included alchemy, folk and religious incense, bathing, cosmetic and medicinal since ancient times. From the Song Dynasty, olibanum had been mainly used as medicinal because of its good effect to treat wounds. In traditional Chinese medicine, olibanum unblocks menstruation, relieves pain and reduces swelling and generated muscles. The medicinal efficacy of olibanum is not much different from ancient to modern. Only the efficacy of replenishing energy and promoting the movement of Qi was rarely mentioned in modern reference. In this article, the historical evolutions of olibanum about original plants, processing and medicinal efficacy were sorted out. The results could provide historical basis for the further development and clinical utilization of olibanum.

In the folk medicine, it was believed that the raw Sanqi could remove blood stasis, swelling and pain, while the cooked Sanqi could replenish blood. This article began with the first record of Sanqi in ancient herbal medicine literature, and the nature, flavor and efficacy of Sanqi, then listed the processing methods and usage of Sanqi recorded in ancient herbal medicine literature, and compared with the modern processing methods. The results showed that the processing methods of raw Sanqi included making powder, chewing, vinegar grinding and wine grinding, in which the method of making powder was still in use, and there were particle size requirements on the Sanqi powder listed in most modern preparation specifications. The processing methods of cooked Sanqi included baking, frying and steaming, in which the method of steaming was still in use, but had some changes. The new processing method was frying with edible oil. The results clarify the history of the processing of Sanqi, and provide a reference for the research and application of the processing methods of raw and cooked Sanqi.

Tianxiong has been used as a Chinese medicinal in China for thousands of years, and the earliest record can be traced back to the Shennong's Classic of Materia Medica. It is effective in dispersing wind, dissipating cold, and replenishing fire to streng-then yang. To clarify the origin of Tianxiong, the present herbalogical study reviewed the ancient and modern literature from the origin, processing, and clinical efficacy. Before the Tang Dynasty, although the description of Tianxiong was quite superficial, an apparent difference between Tianxiong and Fuzi was recognized. In the Tang and Song Dynasties, Tianxiong and Fuzi were mistakenly recognized to be prepared from a same plant since their raw materials came from artificial cultivation. Medical literature in the Ming and Qing Dynasties mostly followed the previous records, with the origin of Tianxiong remaining controversial. There were three mainstream views about the origin of Tianxiong according the ancient medical books. First, Tianxiong was a kind of Aconiti Radix(Chuanwu) without attachment of Fuzi. Second, Tianxiong was the large Fuzi. Third, Tianxiong derived from Aconiti Kusnezoffii Radix(Caowu) about 10 cm in length. By contrast, Fuzi in a large size was simply regarded as Tianxiong in modern times. The processing methods were diversified in the ancient times, and the fire-processing was continuously applied. With the deepening of the research on the efficacy and detoxification mechanism, more methods were discovered, such as processing with ginger juice, child's urine and alcohol. As for modern times, the processing of Tianxiong has not been nearly passed down. The characteristic processing of Tianxiong only handed down in Sichuan province and Lingnan area, which can be discriminated by the last step. The efficacies of Tianxiong can be directly understood from its literal name, including dispersing wind, dissipating cold, and replenishing fire to assist yang. Nowadays, Tianxiong is mostly used to strengthen yang.

Objective:To observe the effect of Changji'an prescription on intestinal permeability in diarrhea-predominant irritable bowel syndrome (IBS-D) rats and explore its mechanism for treatment of IBS-D. Method:Male SD neonatal rats were randomly divided into five groups:normal group, model group, pinaverium bromide group(0.018 g·kg-1), high-dose(33.48 g·kg-1) and low-dose (16.74 g·kg-1)Changji'an prescription groups. Except for the normal group, the IBS-D model was established by the combination of maternal and infant separation+acetic acid stimulation+restraint stress. After drug treatment, the ultrastructure of rat intestinal mucosa was observed by using transmission electron microscopy and the plasma D-lactate level was detected by enzyme-linked immunosorbent assay (ELISA). The expression levels of tight junction proteins Occludin and Claudin-1 were detected by Western blot. The mRNA expression levels of Occludin,Claudin-1 and zonula occluden(ZO)-1 were detected by real time polymerase chain reaction (Real-time PCR). Result:As compared with the normal group, the intestinal mucosal epithelial cells were damaged in IBS-D model group, and the microvilli arrangement was sparse and tight junction was widened, and some were not obvious,and the plasma D-lactate level in IBS-D rats was increased significantly (P<0.05),and the mRNA and protein expression levels of Occludin and Claudin-1 in the colon were decreased and the mRNA expression of ZO-1 was also decreased (P<0.05). After drug treatment, as compared with the model group, all drug-administered groups can repair intestinal mucosal cell damage. Plasma D-lactate level in pinaverium bromide group and high-dose Changji'an prescription group was significantly decreased (P<0.05) while D-lactate level in the low-dose group Changji'an prescription group had a tendency to decrease with no statistical difference. The mRNA and protein expression levels of Occludin and Claudin-1 and the mRNA expression of ZO-1 in the colon of rats in each administration group were higher than those in the model group (P<0.05). Conclusion:The therapeutic effect of Changji'an prescription on IBS-D may be achieved by improving the intestinal permeability.

Schizonepetae Herba and Schizonepetae Spica are well-known Chinese herbal medicines for wind dispersing and exterior releasing. Through textual research on Schizonepetae Herba and Schizonepetae Spica, the discrimination of their medicinal parts in history was clarified, and the processing, the property(nature and flavor), meridian tropism, functions, indications, usage, dosage, and the selection of decoction pieces were compared to provide the basis for clinical application. As a result, the whole herb of Schizonepeta tenuifolia was used as medicine in the early records. The aerial part and the dried spike of S. tenuifolia were used as medicines separately in the Song Dynasty, which was recorded in the Atlas of Materia Medica(Ben Cao Tu Jing). Some ancient classics emphasized that only the dried spike could be used as medicine. The separation of Schizonepetae Herba and Schizonepetae Spica meets the different needs of clinical medication and supports the concept of rational development and utilization of Chinese medicine resources. About ten processing methods for Schizonepetae Herba and Schizonepetae Spica have been recorded since ancient times, and raw and charred drugs were the major products. Raw Schizonepetae Herba is required to be used in sections, whereas raw Schizonepetae Spica in clean preparation. Both charred products should avoid scorching. Schizonepetae Herba and Schizonepetae Spica are similar in the property(pungent, bitter, and warm), meridian tropism(lung and liver meridians, as well as qi and blood aspects), and functions(releasing exterior, dispersing wind, regulating and stopping blood, promoting eruption, dispelling sores, promoting digestion, eliminating alcohol effect, etc.), but Schizonepetae Spica is superior in efficacy. For Schizonepetae Herba and Schizonepetae Spica in traditional Chinese medicinal prescriptions, the raw and charred products are similar in usage and dosage, while their focuses in clinical compatibility vary. The raw and charred products of Schizonepetae Herba and Schizonepetae Spica are widely applied clinically. Decoction pieces of different specifications can result in different efficacies and clinical applications, so medication should be performed with caution.
