Herbs to soothe your digestive tract - Comfrey

Comfrey has a long history in western herbology. It is native to Europe, and still grows wild in many parts of England. It is also known as blackwort, boneset, bruisewort, gum plant, healing herb, salsify, and slippery root.

It is perennial, it has a large root like a turnip, which is black in colour on the outside. It has large hairy broad leaves with small bell shaped flowers, white, cream, purple or pink. Its stem is angular and hairy and grows to about three feet in height. The branches from the stem are located near the top of the plant.
There are about 25 species of comfrey.

Benefits
Comfrey is rich in nutrients containing allantoin, rosmarinic acid, symphytine, echimidine, isobauerenol, sitosterol, tannins, lasiocarpine, phytosterols, triterpenoid, inulin, phenolic compounds, pyrrolisidine alkaloids, and vitamin B12 as well as potassium, phosphorus, calcium and nitrogen as well as linoleic acid.

All these things give it a variety of benefits:
It is good for wound healing and tissue regeneration. It is good for varicose ulcers. Linoleic acid helps alter cholesterol levels and maintain cell function. Tannins are astringent. It has been used to treat gastric ulcers, acne other skin conditions, coughs and asthma. It helps promote secretion of pepsin and is a general aid to digestion. It is possible that the use of comfrey externally helps prevent the improper formation of scar tissue. Comfrey root’s mucilage is partly why it is a digestive aid, as the mucilage coats the digestive tract and destroys amoebic parasites. Comfrey taken as a tea or an expressed juice has been used for stomach upset, stomach ulcers, haemorrhoids and diarrhoea.

How it’s taken
Creams containing extract from the root can be used topically for cuts, acne, sprains, bruises, athletes foot and staph infections. If you are going to use a comfrey root cream, it is important to ensure that the other ingredients in the cream support the aim that you have in using the preparation. For example an overly greasy cream containing comfrey may not help acne.

For topical irritations you can also use the leaves of the plant peeled open and applied as a poultice.
Comfrey is taken internally by using a tea or a tincture made from the root.

Side affects
Comfrey has quite a few potential side effects, to the extent that it has FDA restrictions and warnings attached to it. The ingredients that cause the most worry with comfrey are the pyrrolisidine alkaloids.

These chemicals can cause liver damage, and at worst, death. The comfreys that contain high levels of these substances are Russian comfrey and prickly comfrey. Comfrey can also cause problems for people on potassium restricted diets, as it is high in potassium. It can also be a problem in wound healing situations, as it can cause such rapid healing that if a wound is deep or dirty pus or dirt can be trapped behind the healed skin, and cause abcesses. Comfrey is not recommended for those on anti tuberculosis medications (as it can cause side affects) and comfrey creams and preparations are not recommended for pregnant women.

In summary, comfrey is said by some to be useful taken internally to help with digestive complaints, but it has so many potential side effects that it may be wise to avoid it, except as an external cream.
