What is it?

In herbal medicine the parts we use are the flowering tops and the short, corrugated leaves that are densely covered in a white downy ‘fur’. White horehound is a this low growing, long lived herb which has an unusual, persistent and distinctly bitter taste that is unpalatable to animals so it thrives in hilly pastureland.

How has it been used?

White Horehound has been highly regarded as a cleansing lung tonic for millennia. It has especially been used for bronchitis, whooping cough, chesty colds and loss of voice. It is known as what is called a ‘stimulating expectorant’ which means that it both increases the production and the release of mucus and phlegm from the lungs and bronchial tubes.

White Horehound has additional properties of stimulating the liver (most bitter herbs have an element of this going on) and it was historically recommended for ‘yellowing of the eyes’; i.e. the signs of a congested liver.

John Heinerman writes 'nothing breaks up severe mucus congestion quite like horehound. In fact, I've found it to work a lot better than even coltsfoot! (a remarkably potent lung herb but also rather a dangerous one). One cup of warm horehound tea will instantly loosen impacted phlegm in the throat, lungs and sinuses like you wouldn't believe and relieves a great deal of the misery attending a sinus headache'.

Heinerman's Horehound Tea
~ Ingredients
3 tsps dried White Horehound (or approx 5-6 tsps fresh)
600 mls freshly boiled water
~ Recipe
Pour the freshly boiled water over the herb, cover and allow to steep for 45 minutes with a towel over the top of the saucepan, teapot or plunger to keep it warm. Strain and drink whilst still luke-warm with a squeeze of lemon juice in it and sweetened with a touch of black-strap molasses (honey would also be okay).

Science on White Horehound

~ There have been no clinical trials with people taking White Horehound but there has nevertheless still been some intriguing research into this great herbal remedy. It has been shown to contain a bitter diterpene molecule called marrubiin which Russian and German studies has demonstrated to possess potent expectorant properties, i.e. it loosens catarrh in the chest and helps it to be expelled.

~ Animal studies with White Horehound have shown that in small amounts it helps to normalise irregular heart rhythms but in large amounts can cause them -- this is likely to be related to how extracts of the leaves of White horehound have also demonstrated a potent antispasmodic (i.e. relaxing) action on the kinds of smooth muscles that move the lungs and the blood vessels.

Safety of White Horehound

There are no adverse reactions in people from taking White horehound reported in the medical literature and it is regarded as a safe herb to take by the young and old and in pregnancy or breastfeeding. White horehound is a potent herb and taking a high dose will have a purgative action on the bowel which would indicate a need to ease back on the dosage if this was happening with a daily tonic.

Personal experiences

I have found White Horehound to be especially effective for people with chronic obstructive respiratory conditions and I could hardly imagine treating difficult and chronic conditions such as asthma, bronchitis and recurrent chest infections without its help.

If someone has a tendency to a weak chest then the younger you start them with White horehound the better. It can be tremendous at helping to strengthen the lungs and get clear of congestion but there is a real art to balancing its bitterness in a formula so that the patient will tolerate and take the medicine for the time needed to affect the cure.

If you who are reading this are studying herbal medicine or if you have your own reasons to want to understand this plant ally at a much deeper level then I urge you to get some White Horehound tea or tincture and then, with a quiet and attentive mind, take some and observe for yourself how it makes you feel. This ancient method of experiential learning can give you insights that no amount of academic study can achieve.

Further to this, if you would like to learn more about the ancient art of pulse testing, a simple but powerful way to ask the intuitive intelligence of the body for its responses to a herb by feeling the pulse whilst giving a tiny dose by mouth, read here

Speaking for myself I find it quite uncanny just how much I can feel White Horehound in my own chest when I take some with a quiet mind. I would encourage anyone using it for the first time to feel for themselves just how much it makes them want to breathe deeper and clear their lungs. First of all you are likely to get some very real respect for just how strong a tasting medicine this is and how careful you have to be to get the dose right, not too little and certainly not too much. Stay with the experiment and feel for yourself how the herb gets into your chest and you may get a sense of how it's as determined as a snow-plough when it comes to helping move debris out of the airways!

For short term and rapid affects you can't go past using Horehound as a tea so and, whilst it is an intense flavour and will be hard to swallow, if you try a recipe such as that given by Heinerman above I'm sure you will be impressed with how quickly it can act when needed. For chronic problems small and regular doses of White Horehound will be better and I personally will use around 2-4 mls of Horehound a day in a tincture combined with other herbs to be confident of a strong tonic effect for weakened lungs.

White horehound is is a warming and stimulating expectorant so can safely be taken for long periods even by people who tend towards a cool constitution

For lung weakness or respiratory diseases White horehound combines perfectly with such herbs as Marshmallow, Licorice, Thyme and Ginger.

Constitutional note

Much of the information here about the traditional uses of White horehound is consistent with the model of thinking whereby one may treat problem A with herb B. There is value in this approach in how it helps us pass on useful knowledge to one another but where it falls short is that people are not all cut from the same cloth! White horehound might work brilliantly for one person but less well for another -- why is this?

The reason is that people vary in their constitutions as to whether they are either hotter or cooler and, at the same time, either dryer or damper. This interesting and useful subject is introduced further here

There is an old wisdom in treating the person first and the condition second and in this light White horehound can particularly offer its benefits when a cleansing action is needed in the 'cycle of healing', more about this here

Excerpt from Felter & Lloyd's Kings Dispensatory from 1898

White horehound is a stimulant tonic, expectorant, and diuretic. Its stimulant action upon the laryngeal and bronchial mucous membranes is pronounced and it, undoubtedly also influences the respiratory function. It is used in the form of syrup, in coughs, colds, chronic catarrh, asthma, and all pulmonary affections.

Further Historical Notes
~
The Roman physician Galen highly recommended Horehound for coughs and respiratory problems.
~German Abbess/Herbalist St Hildegard thought it was one of the best remedies for colds.
~The great English herbalist John Gerard wrote "Horehound is a most singular remedy against coughs and wheezings of the lungs'.
~Culpeper wrote about White Horehound that it is a 'remedy for those who are short-winded, have a cough, or are fallen into consumption, it helpeth to expel phlgem from the chest'.
