Comfrey is native to Europe, Asia Minor, Siberia and Iran.<\/p>\n<p>The country name for comfrey was knitbone, a reminder of its traditional use in healing fractures.  The herb contains allantoin, which encourages bone, cartilage, and muscle cells to grow.  When the crushed herb is applied to an injured limb, the allantoin is absorbed through the skin and speeds up healing.  In the past, comfrey baths were popular before marriage to repair the hymen and thus \u201crestore virginity.\u201d<\/p>\n<p>Comfrey was  extremely popular in the 1970\u2019s and early 1980\u2019s, but studies showing toxic pyrroliziidine alkaloids, especially in the root, have tempered the enthusiasm for comfrey.  Recent studies show that leaves harvested during the blooming period (May to September) are very low in alkaloid content.  Suspected carcinogen.<\/p>\n<p>Comfrey contains allantoin, a substance that helps stimulate the growth of new cells and is now used in many cosmetic products.  Commercially prepared comfrey creams and ointments are useful for all kinds of skin irritations, including chafing and bug bites.  Today, we are more cautious about taking comfrey internally, because it contains pyrroliziidine alkaloids, compounds known to cause liver disease if taken over a long period of time.  The FDA is investigating pyrroliziidine alkaloid levels in domestic comfrey.  There are other safer herbs that can be used in its place, such as peppermint, balm, and ginger.<\/p>\n<p>Comfrey was known to the Crusaders as a wound herb, since it is unrivaled in repairing broken bones and battered bodies.<\/p>\n<p>The book Old Ways Discovered states, \u201cThe mucilaginous root is employed by colormakers; it is also employed to correct the brittleness of flax and the roughness of wool in spinning.  It is said that a decoction of the root is of great importance in the process of tanning.\u201d<br \/>\n<a href=\"#top\"><font size=\"-1\">Back to Top<\/font><\/a><\/p>\n<hr size=3 width=80% COLOR=\"#004040\" align=\"center\">\n<h3><a name=\"Uses\">Uses<\/a><\/h3>\n<p>Acts as a blood cleanser.  Beneficial for asthma, coughs, catarrh, flu, ulcers, swelling, varicose veins, perineal tears, diaper rash, cradle cap, cramps, tuberculosis, pain, and burns.  Also good for the stomach, kidneys, bowels, and lungs.<\/p>\n<p>A decoction of the rootstock makes a good gargle and mouthwash for throat inflammation, hoarseness, and bleeding gums.  Drink it to take care of most digestive and stomach problems, for intestinal difficulties, anemia, scrofula, pimples, for excessive menstrual flow, heal broken bones, and to stop spitting blood.  Powdered rootstock can also be taken internally for bloody urine (hematuria), leukorrhea, diarrhea, gastro-intestinal ulcers, gout, dysentery and persistent coughs.  Externally, use the powder as a hemostatic agent, and make a poultice for wounds, boils, abscesses, wounds that refuse to heal, leg ulcers, bruises, sores, broken bones, sprains, and insect bites.  The hot pulp of the rootstock makes a good external application for bronchitis, pneumonia, coughs, pleurisy, and for the pain, and inflammation of pulled tendons.  Add the rootstock to the bath water regularly for a more youthful skin.<\/p>\n<p>Makes an excellent liquid fertilizer for garden and houseplants (allow leaves to decompose in a container of water).  Add to the compost pile; use only wilted leaves, however, so they do not take root in the compost pile.<\/p>\n<p><center><figure class=\"wp-block-embed wp-block-embed-youtube is-type-video is-provider-youtube epyt-figure\"><div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\"  id=\"_ytid_44975\"  width=\"650\" height=\"366\"  data-origwidth=\"650\" data-origheight=\"366\" src=\"https:\/\/www.youtube.com\/embed\/6_XMkNWET3I?enablejsapi=1&autoplay=0&cc_load_policy=0&cc_lang_pref=&iv_load_policy=1&loop=0&rel=1&fs=1&playsinline=0&autohide=2&theme=dark&color=red&controls=1&disablekb=0&\" class=\"__youtube_prefs__  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe><\/div><\/figure><\/center><br \/>\n<a href=\"#top\"><font size=\"-1\">Back to Top<\/font><\/a><\/p>\n<hr size=3 width=80% COLOR=\"#004040\" align=\"center\">\n<h3><a name=\"Dosages\">Formulas or Dosages<\/a><\/h3>\n<p><strong>Decoction:<\/strong> boil 2 tsp. rootstock in 1 cup water or wine.

Use is restricted in Australia, New Zealand, Canada, and Germany.<\/p>\n<p>Avoid use of comfrey with edema, obesity, or malabsorption.<\/p>\n<p>Use only under careful medical supervision.  Do not use for longer than 3 months at a time.
