• In the Bensky/Clavey/Stoger Materia Medica, this substance is classified as “obsolete,” which the authors claim is due to its toxicity. I have not seen Peng sha referred to as toxic in other resources on Chinese herbs. However, in the Wikipedia entry on borax, its toxicity is discussed at length. Here is an excerpt:
“Borax, sodium tetraborate decahydrate, is not acutely toxic. Its LD50 (median lethal dose) score is tested at 2.66 g/kg in rats: a significant dose of the chemical is needed to cause severe symptoms or death. The lethal dose is not necessarily the same for humans.
“Sufficient exposure to borax dust can cause respiratory and skin irritation. Ingestion may cause gastrointestinal distress including nausea, persistent vomiting, abdominal pain, and diarrhea. Effects on the vascular system and brain include headaches and lethargy, but are less frequent. ‘In severe poisonings, a beefy red skin rash affecting palms, soles, buttocks and scrotum has been described. With severe poisoning, erythematous and exfoliative rash, unconsciousness, respiratory depression, and renal failure.’
“Borax was added to the Substance of Very High Concern (SVHC) candidate list on 16 December 2010. The SVHC candidate list is part of the EU Regulations on the Registration, Evaluation, Authorisation and Restriction of Chemicals 2006 (REACH), and the addition was based on the revised classification of Borax as toxic for reproduction category 1B under the CLP Regulations. Substances and mixtures imported into the EU which contain Borax are now required to be labelled with the warnings “May damage fertility” and “May damage the unborn child”.”

Eric Brand:
Xue Jie (Daemonoropis Resina) is a fascinating substance. Also known as Dragon’s Blood, Xue Jie has been used for hundreds of years in many different cultural contexts. Xue Jie is a tree resin that has been used as a medicine, incense, and dye since ancient times. It was recorded in Greece by Dioscorides and appeared for the first time in Chinese medicine in the Lei Gong Pao Zhi Lun (Master Lei’s Treatise on Drug Processing), written in the Northern and Southern Dynasties period (420-589 CE). It later appeared in the Tang Ben Cao (Tang Materia Medica), the first Imperial textbook on materia medica.
Xue Jie is used for a diverse range of purposes. In Chinese medicine, it is said to quicken the blood, stanch bleeding, and engender flesh. It is a major medicinal in traumatology and is also used to treat bleeding in the upper GI tract. Beyond injuries and bleeding, if we look at its applications in modern Chinese medical gynecology, we find that Xue Jie is an incredibly important medicinal in empirical formulas to treat endometriosis.
The importance of Xue Jie in endometriosis is evident when examining modern Chinese textbooks on TCM gynecology. Its claim to fame lies in expelling old blood stasis so that new blood can be engendered; in fact, its Chinese name literally means “exhausted (spent) blood.” Looking at the treatments for endometriosis relative to traditional TCM disease categories such as painful menstruation or concretions and conglomerations (zheng jia), we see that the formulas selected for the same patterns are consistent but nearly all the endometriosis formulas add in Xue Jie. Thus, clearly the experts in China know something about Xue Jie that most of us do not.

SD: Camphor oil is obtained from a tree (Cinnamomum camphora), and like cardamom, the essential oil of the tree contains a large number of terpenoids (mostly, the same ones as in cardamon, but in different proportions). Camphor was collected at least as early as the 9th Century. In 1676, the trees were brought to Europe for cultivation. In the following century, it was also introduced to several other countries, including the U.S. Prior to World War II, the world use of camphor was about 5,000 tons per year; 80% of this came from Taiwan (the Taiwan camphor tree yields 44% camphor from its leaves, a particularly high level). During the U.S. Civil War, the demand for camphor (used primarily as a medicinal) was so high that the U.S. contracted for the entire Taiwan supply. It was even proposed that an effort be made to purchase Taiwan (then called Formosa) in order to monopolize the camphor trade. It is perhaps for this reason that Japan acquired Formosa in 1895.
Camphor oil was a popular medicinal in the U.S. until about twenty years ago when several instances occurred in which children were fed camphor oil by parents who failed to distinguish it from castor oil. The pure camphor oil is toxic in the doses for which castor oil is used. Also, the U.S. Food and Drug Administration worried that topically applied camphor oil would penetrate the skin in sufficient amounts that it could cause trouble for persons with cardiac disorders who were taking various medications. As a result, it is no longer possible to purchase camphor oil for household use in the U.S.
Like borneol, camphor has been used as an antiseptic, antispasmodic, carminative, cardiac stimulant, respiratory aid, and anthelmintic. It is often used in treating congestive problems such as bronchitis and emphysema. Camphor is also used in preparation of foods, being an ingredient of vanilla and peppermint flavors, and incorporated into formulations of soft drinks, baked goods, and condiments. In modern Chinese medicine, camphor is most often reserved for external application, while borneol is used both internally and externally. Synthetic camphor, often made from by chemically modifying pine tree resins (turpentine), is now widely used as a substitute for the natural product.
Camphor and the chemically related compound camphene are found in: cardamom, saussurea, ginger, magnolia, curcuma, cinnamon, nutmeg, and cyperus.
