The Energetics of Chen Pi in Puerh


I have read many good puerh articles and blogs about the medicinal properties of chen pi which is increasingly being added to shu puerh productions by western puerh vendors.  Many of these articles speak about the addition of chen pi either to enhance taste and to fight colds- both of these are true.  However, most don’t speak to the deeper reasoning as to why chen pi is added to shu puerh…

There is only one herb in Traditional Chinese Medicine that becomes more potent with age.  That herb is Chen Pi and it is correctly translated as aged tangerine peel.  I have been told that a tangerine peel that is freshly dried is not chen pi.  Chen pi is aged and as it ages it continues to become more potent as a medicinal as chemical changes take place.  If you have ever tried antique chen pi it tastes very different than 10 year old chen pi which tastes different than 3 year old chen pi.  As it ages it dries and loses mass to become a more concentrated medicinal.  Therefore it will weigh less as it ages but will be more concentrated medicine.  Chen Pi is also the only herb that increases in price the longer it ages.  Very old or antique chen pi is very valuable as its Qi becomes stronger and deeper … sound familiar?

It has frequently been mentioned that chen pi can treat colds and coughs this is because chen pi enters the Lung and its taste is pungent.  Puerh doesn’t enter the Lung and its taste is not considered pungent in Traditional Chinese Medicine.  So the addition of chen pi expands the medicinal effect and taste of puerh.  Chen Pi also enters the Spleen and Stomach and its taste is bitter and warming.  Shu puerh also enters the Spleen and Stomach and is bitter and warming.  The combination of chen pi with shu puerh acts to mutually accentuate the individual properties of each making the effect on the digestion even stronger than the sum of its parts.  Therefore it should also be stressed that when chen pi is added to shu puerh it also makes for a much more powerful digestiff after a large meal.

So… who will be the first vendor to press antique chen pi into their shu ?

Peace

  1. My problem with TCM is that all this stuff about what chen pi can apparently do, can all be stated without evidence and everyone just goes along with it.

      I think it’s actually the opposite. People’s experience with TCM as such an effective medicine leads them to state it with confidence.

  2. I actually saw people in China drinking very old chen pi with puerh so they would use a bit of each basically. I always assumed shu puer was more sweet than bitter actually... .

    1. Curigane,

      You are right. Tea is considered bitter and sweet in TCM- the more it ages, the more warmth it acquires. It also becomes less bitter and more sweet. The pile fermentation of shu puerh gives it both more warmth and sweetness and less bitter.

      I missed that. Thanks for mentioning that.

      Peace

  3. Chinese herbs are fairly well researched, and have a long history of documented clinical use. My favorite herbal pharmacopeia has a good monograph on chen pi including clinical use, chemical components, toxicology, pharmacological effects, and research. Other more clinically significant herbs tend to have more research.

      Agree 100% with you. I also have an insanely thick, thousands of pages herbal TCM pharmacopeia. There is tones of research in there!

      Peace

  4. Sounds like we might have the same book. I prefer Chen's single herbs book, as well as his formulas book. Mighty tomes indeed.

      Yes we do! I have both. Hahaha I have both of Bensky’s as well. His books focus more on the traditional reference to source texts, traditional theory, and traditional and alternative preparations of herbs.

      For instance, Bensky mentions that Chen Pi is traditionally prepared by sun drying the tangerine peels but periodically spraying them with water. The spraying with water part is interesting because I believe it was done to ensure that the volatile oils of Chen Pi aren’t evaporated in the heat of the sun- although he doesn’t state that directly. He does state that the quality of Chen Pi is known from the vibrancy of its odour.

      Peace
