Yellow dock provides a good example of an herb used to assist opposing conditions. Because of the mixture of active constituents, it acts as a regulator and balancing agent on the digestive system, assisting both constipation and diarrhea. It also contains tannin, calcium oxalate, vitamin B1, lapodin (a naphthalene derivative), iron, sulfur, and a volatile oil. The leaves contain vitamin C, iron, and oxalic acid. Use it in moderation, as oxalate crystals mechanically penetrate tissue, thus creating small wounds. Note: Freezing or boiling destroys oxalate crystals. The seeds are high in tannin, which acts as an astringent. Yellow dock is the most medicinally active variety of the dock family. All members of the dock family store iron in their roots, and it is this mineral plus yellow dock's specific active constituents that make it an excellent blood purifier and builder. Research has shown that yellow dock builds up white blood cells without attacking any one particular organism. This makes it a useful remedy wherever infection is present, as the resistance to infection remains after the initial infection. Yellow dock is an alterative with a specific short-term action plus a long-term immune response enhancer. Yellow dock stimulates the liver and is often combined with dandelion Taraxacum officinale. It is also reported to have anti-tumor properties; however, the constituent responsible for this action has not yet been isolated.
