Houndstongue
(Cynoglossum officinale)
I have included Houndstongue because it is a widespread native plant with many of the same medicinal uses as Comfrey. I am not all that familiar with the plant, so the information and photographs have been gleaned from books such as The Physician's desk Reference for Herbal Medicine. The pictures have been gathered from copyright free internet sites. I have given credit to the photographers. If any images contained here are copyrighted, please let me know, and I will remove them immediately.

Habitat:

Parts Used:
Leaves, stems, roots
Culinary Uses:
None. Like Comfrey, Houndstongue contains pyrrolizidine alkaloids. It is therefore not recommended for internal use. Pyrrolizidine alkaloids are hepatotoxic, and hepatocarcinogenic in effect. Meaning they are toxic and cancer causing to the liver.

Taste: Salty/Sweet
Thermal: Cooling
Humidity: Moistening
Medicinal Uses:
This plant is used medicinally. It contains Allantoin, a compound which aids in cellular regeneration. It is therefore quite effective at healing wounds. The Physician's Desk Reference For Herbal Medicines also lists usages such as antidiarrheal, and an expectorant. It further says it has been used as an analgesic, both internally, and externally, and as a cough sedative, although I think the author meant cough suppressant.
Houndstongue supposedly functions just as well as comfrey, but is much more readily found in the wild. I cannot attest to this fact, as I have not used the plant. It was brought to my attention by an acquaintance.
Like comfrey, C. officinale contains pyrrolizidine alkaloids. It is therefore not recommended for internal use. Pyrrolizidine alkaloids are hepatotoxic, and hepatocarcinogenic in effect. Meaning they are toxic and cancer causing to the liver. There have been studies where rats were injected with enormous amounts of pyrrolizidine alkaloids, and some developed liver failure, while others developed cancer of the liver. For years, I have used Comfrey, another plant containing pyrrolizidine alkaloids, with no ill effects.

Herbal Preparations For Cynoglossum officinale
Infusion
Part Used: Above ground plant (In Summer)
Plant State: Fresh
Place 2 ounces of the fresh chopped plant material into a quart mason jar, and fill the jar with almost boiling water. Cover the jar, place it in a sunny location, and let it sit for 8 to 10 hours. If refrigerated, the infusion will last a couple of days.
Dosage: 2-4 oz As Needed
Infusion
Part Used: Root (In Autumn)
Plant State: Fresh
Place 2 ounces of the fresh chopped root into a quart mason jar, and fill the jar with almost boiling water. Cover the jar, place it in a sunny location, and let it sit for 8 to 10 hours. If refrigerated, the infusion will last a couple of days.
Dosage: 2-4 oz As Needed
Infused Oil
Part Used: Above ground plant (In Summer)
Plant State: Fresh
Natural Solar infusion method:
In a quart mason jar, thoroughly mix 2 ounces of fresh chopped herb and 6 ounces by weight of the oil of your choice. Cover the jar and place in a sunny spot for a month or so. Strain your oil, return to the cleaned jar and store in the refrigerator until needed.
Crock Pot Method: (My favorite)
Place 2 ounces of fresh plant material and 6 ounces by weight of grape seed oil into a crock pot. Mix thoroughly, set the dial to its lowest setting, and allow to heat uncovered for 12 hours. After this time has elapsed, place the cover on the crock pot and turn the switch to off. Allow the pot to sit covered until the following morning. Then turn the crock pot once again to its lowest setting, remove the cover, and allow to heat uncovered for an additional 12 hours. Once this time has elapsed, allow the oil to cool enough that you can touch it without burning yourself, and then strain the plant material out. Now place the strained infused oil into a pint-sized mason jar and store it in the refrigerator until needed. (When straining my infused oils, I place a coffee filter into a fine metal sieve, and set the sieve over a glass bowl. I then pour the mixture into the strainer, and let it sit until all the oil has drained. Once it appears that it has completely drained, you will notice that there is much less than the 6 ounces of oil you started with. I usually take a large wooded spoon, or something else heavy, and pack the mixture into the strainer. I am always surprised how much oil is still released from the plant material. You can expect to yield just over 5 ounces by weight of your infused oil)
Dosage: You can apply infused oil topically as needed. You can also follow the directions below to turn your infused oil into an ointment or salve.
Ointment or Salve
Infused oils are turned into ointments and salves. I have found a 5:1 ration by weight of infused oil to bees wax yields the best consistency of ointment. In a medium saucepan, heat 5 ounces, by weight, of your previously prepared infused oil over low heat. When the oil is hot enough, stir in 1 ounce of grated bees wax. When the wax is completely dissolved, dip the back of a clean cold spoon into the mixture. Allow it to cool and solidify. If you find the ointment is too hard, add a little more oil, if you find it is too soft, add a little more bees wax, until you reach your desired consistency. To make an even more luxurious feeling ointment, before it cools, try adding 1 tablespoon of lanolin to your ointments. If you are anything like me, you will love the luxurious texture, and soothing effect it has on your skin.
Dosage: Apply topically as needed
Tincture
Part Used: Above ground plant (In Summer)
Plant State: Fresh
Alcohol Percentage: 75%
Plant to Alcohol Ratio: 1:2
Label a quart mason jar with the plant name, the part of the plant used, the percentage of alcohol used, and the date the tincture was started.
Fill the jar to the neck with chopped fresh leaves, then pour in 150 proof Everclear (Or the highest percentage available to you). Place a lid on the mason jar, shake it well, and place the jar in a dark cupboard. Once a day for the first 7 days, take the jar out of the cupboard and shake it well. Place the jar back into the cupboard, and leave it soak for another 3 weeks. After the tincture has soaked for 30 days, remove it from the cupboard and strain out the spent plant material. Your tincture will remain viable for 2-3 years.
Dosage: Apply 3-5 ml externally to affected areas.
