Protect and heal your lungs from smoke damage – some herbs you may have growing near you.

This Summer has been a catastrophic time with bushfires rampaging through large portions of New South Wales, Victoria and also affecting Queensland and South Australia. The loss of human and animal lives, and loss of property is devastating. In addition to this, the air quality has been deemed ‘hazardous’ on many days, and likely will not be improving within the next few weeks.

Even if not directly affected by the fires, the vast majority of people living in New South Wales have been living admist smoke haze, and many other states will be the same. For those that live closer to the fire affected areas and those who are fighting the fires (thank you thank you thank you), they will be affected by the smoke even moreso.

The Impact of Smoke on Health

The impact of smoke on respiratory health can be severe for some. For those who already have breathing difficulties such as those with asthma or cardiovascular problems, and for children and the elderly this can be especially problematic.

A NSW Ambulance superintendent, Brent Armitage, said paramedics were attending up to 100 respiratory-related call-outs per day and the state’s health department warned residents to stay indoors as much as possible amid “unprecedented” smoke pollution.

Particles that are smaller than the eye can see are some of the most hazardous components of smoke. The rating of this – PM (particle matters) has been rated as hazardous in many instances in New South Wales, and in Canberra at the time of writing this article it was 926. To give you some context, a good rating is below 10.

You can find details on air quality near you here: https://aqicn.org/map/australia/

Fine particle matters – known and measured globally as PM2.5 – are invisible to the human eye. They are coated in chemicals such as lead and are most worrying because they penetrate deep into the lungs.

Australia’s clear air standard is a PM2.5 level of eight micrograms per cubic metre. By comparison, smoking a single cigarette produces 20 micrograms per cubic metre.

Recent readings in Sydney have been as high as 734 micrograms – the equivalent of about 37 cigarettes.

The particles are often compounds which contain chemicals detrimental to our health such as heavy metals. While not as toxic as industrial pollution, any by product of something being burnt is harmful to health.

Get the Right Mask

For most of us, sitting inside out of the smoke seems like the best solution we have. But when the fires are going for as long as they are it becomes unrealistic to hide inside all the time. And for those that are fighting the fires, this is also not an option.

Wearing a mask may help, but make sure it is the right type. Some masks that people are wearing to filter the smoke may not be sufficient to reduce in the inhalation of the fine particles. Medical masks do not filter the fine particle matter.

P2 masks or PR respirators are an option to help filter the smoke and fine particular matter which can be found in most hardware shops.

How Herbs Can Help

If your backyard is still growing, step outside on one of the cooler moments and look for some herbal helpers which may be utilised for supporting lung health.

I still remember a phrase that “what you are looking for, is also looking for you” and this is so often relevant for herbal medicines. In this instance, you may find that in your garden a herb is growing, waiting for you to discover it.

The herbs I have included in this list are those I feel are resilient to the heat and rampant so there is a good chance are growing near you.

Many other herbs exist that can also be supportive for lung health such as Mullein, Licorice, Mashmallow, Licorice and Elecampane. Get in touch with a herbalist if you would like a herbal formula or tea created for you.

The impact of the bushfires and smoke are far greater than just the impact on one’s lungs. If you need additional support for stress and trauma please seek help.

Nasturtium

Did you know that this plant has many medicinal benefits? It’s often grown for it’s pretty flowers and distinctive leaves which are sometimes included in meals. All parts of this plant are edible so can be used as a decorative garnish for meals, a peppery addition to the flavour profile, or the fruits can be pickled as an alternative to capers.

It is additionally quite medicinal, having an affinity for the respiratory and urinary system. It contains pungent compounds which can assist the lungs in eliminating unwanted substances. It has pulmonary antiseptic properties and helps to reduce inflammation.

Herbs which have the action of ‘expectorants’ are indicated for smoke exposure, as they assist the lungs in the act of elimination. This may be initially seen through an increase in coughing and expulsion of mucous. Nasturtium contains expectorant properties, and also assists in the elimination of mucous in the sinuses and nasal passages³.

Use the leaves or flowers in salads or as a garnish on dishes which would benefit from a peppery taste. If you would like to try an infusion, take 15-20g chopped leaves and/or flowers and infuse in hot water for 10 minutes. Drink 3 times daily.

Mallow

One of my favourite herbs is Marshmallow, Althea officinalis – not the squishy confectionary but a plant with soothing mucilaginous properties that helps and calms the respiratory, urinary and digestive tract. In the same family as this herb is Mallow, an easilly found group of plants which contain similiar properties (also referred to as Cheese Weed, Common Mallow Malva sylvestris, Small-flowered Mallow Malva parviflora, Dwarf Mallow Malva neglecta or Cheese Plant).

Mallow is not as much of a mucilaginous powerhouse as Marshmallow, but it can be found in many people’s backyards and still packs a medicinal hit.

Mucilage in a herb is soothing to your tissues, especially the mucous membranes, which predominately dwell in your respiratory tract and digestion. If you chew on a herb rich in mucilage you may find it turns almost jelly-like in your mouth. This compound is responsible for many of it’s soothing and anti-inflammatory properties.

Mallow helps to soften and expel mucous and substances in the lungs, however it is also beneficial emotionally as it can soften pain and help you to express and release emotions around trauma.⁴

The leaves of mallow can be added to dishes as a thickener, or you can make a tea or glycetract from it.

Ribwort

Once you know this herb you will find it everywhere. I commonly find it growing along footpaths but you are best to source it from somewhere that has not been exposed to chemical pollution.

Narrow leaf plantain or Ribwort, Plantago lanceolata is one of my go-to herbs for chronic or inflammed respiratory conditions.

Like Mallow, this herb also contains mucilages but is classed as a ‘tropho-restorative’, which means it has healing and restoring properties to the tissues which it targets – in the case of Ribwort that is the respiratory tract. It is a mild expectortant but is predominately a soothing repairing herb.

The younger leaves can be used in salads, smoothies or cooked.

How to use the herbs

In the instance of these herbs if you can find them, they can be included in your cooking or made into teas or infusions.

If you cannot locate these herbs but would like to make use of them contact your local herbalist or naturopath to source these.

If you are located near me and have been affected by the bush fires please get in touch so I can help you our with a tincture.

The post Looking after your lungs with local herbs during bushfire season. appeared first on Alison Mitchell Naturopath.

In a recent podcast I interviewed medicinal mushroom expert Jeff Chilton. One of the points we spoke about that was enlightening for me is the diversity of ways that one popular medicinal mushroom can be grown and sold, Ophiocordyceps sinensis– sometimes referred to as Caterpillar fungus.

This fungus (which isn’t quite a mushroom) is so interesting, in many ways. The way it grows in it’s natural state is a bit scary but it’s also interesting because of how many benefits Cordyceps has.

There are lots of different species of the Cordyceps fungus, but they all have something in common. They are a parasitic fungus. Each type of Cordyceps as it’s own host, and that is the body of an insect, a different insect for every cordyceps. There’s one type of Cordyceps fungus that exists in the jungles of Brazil and targets ants. It takes over the body of the ant it’s inhabiting and effectively turns it into a zombie, controlling it’s host body to get to a place that is just right for the fungus to grow. This type of Cordyceps is called Ophiocordyceps unilateralis. 

Scientists who have been studying the fungus have found that it can control the ants by growing into the spaces around the ants muscles and controlling the muscles like a puppet. It leaves the brain intact to keep the ant alive, but severs the connection between the ants brain and it’s muscles, so it’s quite possible the ant is trapped in a body that is acting against it’s will. Freaky stuff.

You probably know already that I’m a nerd in more than one form – I love digging through scientific literature and reading text books, but I also love to read fantasy fiction and play video games. One of my all time favourite video games is the Playstation game ‘The Last of Us’. This game takes the zombie apocalypse concept and puts a different spin on it to the standard virus concept – and it’s all to do with our friend the Cordyceps fungus. The premise is much like how the fungus affects ants, but with humans as the victim, and so we have a group of zombies infected with the Cordyceps fungus running around biting people. Of course this is fiction, and like all good fiction there’s a nod to reality.

If you don’t like video games I have heard this is coming out as a movie soon! I for one am excited to see it.

Thankfully, the type of Cordyceps mushroom humans use as medicine is quite different – no mind control here! Also, Cordyceps can’t infect humans so if you ever encountered the ‘zombie’ form, you wouldn’t have an issue then either.

Medicinal Cordyceps

This fascinating fungus has been used in traditional Chinese medicine, however the form that is originally sourced from is incredibly rare and expensive. Wild Ophiocordyceps sinensis takes residence in the caterpillar of the ghost moth. The fungus spreads throughout the caterpillar, consuming the nutrients of it’s host, and the caterpillar then expires. It is gradually covered by dirt and over time a fungal protusion will emerge from the caterpillar, a blade-like mushroom body growing from one end. The size of the mushroom is tiny, and when harvested the caterpillar is usually taken along with it. Its common Chinese name is “Winter worm, summer grass” because of the life cycle of the pair.

There isn’t anyway to cultivate this particular strain of mushroom so it has to be wild harvested, but this is damaging to the environment. So, scientists have found a way of growing the mycelium of this mushroom by growing it on liquid fermentation (no caterpillars involved) but it doesn’t grow a fruiting body. The mycelium has been shown to have a similiar chemical profile to the wild Cordyceps and is used in many cordyceps supplements – this product is known as Cordyceps CS-4.

There is also a different type of Cordyceps called Cordyceps militaris, and researches have found that the chemical profile is actually quite similiar to that of the fruiting body of the Cordyceps sinensis, in fact some of its constituents are actually higher than C. sinensis, making this a great alternative.

Benefits of Cordyceps

A lot of the claims for Cordyceps come from the traditional use of Cordyceps sinensis. It has been used for:

• Boosting energy
• Supporting athletic performance
• A tonic for those who have been recently ill
• A tonic for the post-partum period
• A sexual tonic, boosting libido
• To boost lung health, helpful for coughs and asthma

The cultivated mycelium known as CS-4 and the similiar Cordyceps militaris have been found to have properties which support these traditional uses. They have been shown to improve physical performance and fitness in athletes, to improve energy and to support immune health.

How to Take Cordyceps

Like most medicinal mushrooms you need to take it consistently for a few weeks to observe an effect.

You can mix the powder into your food or drink (such as coffee) or take the capsules.

The dosage varies on the form that you choose, so follow the instructions on the product or take as advised by your practitioner.

Always look for quality – look for CS4 or the Cordyceps militaris fruiting body
