Bennett in a research article published by the <a href=\"https:\/\/www.herbalgram.org\/resources\/herbalgram\/issues\/78\/table-of-contents\/article3244\/\">American Botanical Council<\/a>.&nbsp;<\/p>\n\n\n\n<p><a href=\"https:\/\/case.fiu.edu\/about\/directory\/profiles\/bennett-bradley.html\">Bennett<\/a> is a professor of biological sciences and an ethnobotanical expert at Florida International University. He elaborates that these physical characteristics include shape, color, texture, and smell, which reveal their therapeutic value. Bennett alludes to the plant physiologist and historian R.H. True, who summed up the Doctrine of Signatures more succinctly: \u201cEvery plant having useful medicinal properties bears somewhere about it the likeness of the organ or of the part of the body upon which it exerts a healing action.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Examples of the Doctrine of Signatures in TCM<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><br>Walnuts<\/h3>\n\n\n\n<p>Walnuts are arguably the best example of the DOS in the West. This brain-boosting food resembles the two hemispheres of the brain. Even its shell is shaped like the human skull.

What\u2019s the benefit of Yu Zhu, according to the Doctrine of Signatures?&nbsp;<\/p>\n\n\n\n<p>In TCM, this visual similarity is associated with the herb&#8217;s traditional use for moistening and lubricating the lungs and throat. If your Yang Qi is excessively drying you out because you\u2019re running too hot, Solomon&#8217;s Seal may help generate bodily fluids and nourish cooling Yin energy. TCM doctors often use Yu Zhu for dry coughs, dry throat, and other respiratory conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Chinese Yam&nbsp;<\/h3>\n\n\n\n<p>The rhizome\u2014sort of like a root but technically a different part of the plant\u2014of the Chinese Yam (<a href=\"https:\/\/www.activeherbwholesale.com\/Single-Herb-Extracts\/Shan-Yao-Chinese-Yam-Extract-Granules\" class=\"ahw-link\" style=\"display: none\" target=\"_parent\" rel=\"noopener noreferrer\">Shan Yao<\/a><a href=\"https:\/\/www.activeherb.com\/extract\/shanyao.shtml\" class=\"retail-link\">Shan Yao<\/a>) <a href=\"https:\/\/encrypted-tbn3.gstatic.com\/licensed-image?q=tbn:ANd9GcSqm1ZR7p6MDd_CkWtqsiOu0MyyFTCA3CHyWkymcrenBf-W5wn6Fb3LyEaU1SJf4q22NnA8ObDC4fZ0vcw\">resembles the human spleen<\/a> in shape.

But in TCM, its properties are anything but scorching. In fact, Chrysanthemum possesses cooling properties that may clear heat from the Liver. It is commonly used in eye-related formulas because the Liver channel opens into the eyes. This makes Ju Hua, according to the Doctrine of Signatures, an herb that supports occasional redness, dryness, and irritation of the eyes.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symbolic and Energetic Properties of Herbs<\/h2>\n\n\n\n<p>As stated, other physical attributes of herbs besides shape may explain their actions according to the DOS theory. Beyond the physical resemblance, there exists a symbolic and energetic meaning associated with certain plants. For example, a climbing vine may symbolize growth and upward movement. Thus, if someone has stagnant Qi in the Liver channel, manifested by anger, a climbing vine such as <a href=\"https:\/\/www.activeherbwholesale.com\/Single-Herb-Extracts\/Jiao-Gu-Lan-Jiaogulan-Extract-Granules\" class=\"ahw-link\" style=\"display: none\" target=\"_parent\" rel=\"noopener noreferrer\">Jiao Gu Lan<\/a><a href=\"https:\/\/www.activeherb.com\/extract\/jiaogulan.shtml\" class=\"retail-link\">Jiao Gu Lan<\/a>\u2014an <a href=\"https:\/\/www.activeherb.com\/blog\/adaptogens.html\">adaptogenic herb<\/a>\u2014may help support the Liver and promote Qi circulation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Doctrine of Signatures in TCM Conclusion<\/h2>\n\n\n\n<p>Western medicine may scoff at the Doctrine of Signatures, regarding it as an amusing folk sideshow. However, in TCM and many other medical systems, the DOS can be used as a valuable and intriguing tool in the arsenal of TCM practitioners. Rooted in ancient wisdom and observations of nature&#8217;s patterns, this fascinating theory provides valuable insights into the therapeutic properties of herbs and their potential applications in addressing specific health issues.<\/p>\n\n\n\n<p>This is not to say TCM professionals dispense formulas to their patients solely based on DOS theory. We also have centuries of experience and modern research studies to thank for appropriate prescribing and dosing guidelines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ever wonder how ancient Chinese medicine physicians figured out the specific actions of herbs?
