Home Remedies for cough
Coughs
play a role in clearing irritants and infections from the body, but persistent
coughing can be annoying. The best treatment for a cough will depend on its
underlying cause. There are many possible causes of coughs, including
allergies, infections, and acid reflux.
Some
natural remedies may help to relieve a cough. However, it is important to
remember that the U.S. Food and Drug Administration (FDA) do not monitor herbs
and supplements, so people who use them may be at risk of using low-quality
products and impurities.
People
who want to use natural remedies to treat their cough should research sources
and brands. They should also be aware that some herbs and supplements can
interfere with medications, which may result in unwanted side effects.
If a
cough is severe or persists for more than a few weeks, it is essential to seek
medical advice.
Twelve
natural cough remedies
People
use a range of natural remedies to try to treat a persistent cough. Here, we
look at 12 of these remedies in more detail.
1.
Honey tea
According
to some research, honey may relieve coughs.
A study on treatments for
nighttime coughing in children compared dark honey with the cough-suppressing
medication dextromethorphan and with no treatment.
The researchers reported that honey
provided the most significant relief from coughing, followed by
dextromethorphan.
Although the benefits of honey over
dextromethorphan were small, parents rated honey most favorably of all three
interventions.
To use honey to treat a cough, mix 2
teaspoons (tsp) with warm water or an herbal tea. Drink this mixture once or
twice a day. Do not give honey to children under 1 year of age.
2. Ginger
Ginger may ease a dry or asthmatic
cough, as it has anti-inflammatory properties. It may also relieve nausea and
pain.
One study suggests that some
anti-inflammatory compounds in ginger can relax membranes in the airways, which
could reduce coughing. The researchers mainly studied the effects of ginger on
human cells and animals, so more research is necessary.
Brew up a soothing ginger tea by adding
20–40 grams (g) of fresh ginger slices to a cup of hot water. Allow to steep
for a few minutes before drinking. Add honey or lemon juice to improve the
taste and further soothe a cough.
Be aware that, in some cases, ginger tea
can cause stomach upset or heartburn.
3.
Fluids
Staying
hydrated is vital for those with a cough or cold. Research indicates
that drinking liquids at room temperature can alleviate a cough, runny nose,
and sneezing.
However,
people with additional symptoms of a cold or flu may benefit from
warming up their beverages. The same study reports that hot beverages alleviate
even more symptoms, including a sore throat, chills, and fatigue.
The
symptom relief was immediate and remained for a continued period after
finishing the hot beverage.
Hot
beverages that may be comforting include:
·
clear
broths
·
herbal
teas
·
decaffeinated
black tea
·
warm
water
·
warm
fruit juices
4.
Steam
A wet
cough, which is one that produces mucus or phlegm, may improve with steam. Take
a hot shower or bath and allow the bathroom to fill with steam. Stay in this
steam for a few minutes until symptoms subside. Drink a glass of water
afterward to cool down and prevent dehydration.
Alternatively,
make a steam bowl. To do this, fill a large bowl with hot water. Add herbs or
essential oils, such as eucalyptus or rosemary, which may also relieve
decongestion. Lean over the bowl and place a towel over the head. This traps
the steam. Inhale the vapors for 5 minutes. If the steam feels hot on the skin,
discontinue until the skin cools down.
People
with a wet cough or chest congestion may also wish to follow the
recommendations of the National Heart, Lung, and Blood Institute (NHLBI)
and use a cool-mist humidifier or steam vaporizer in their home.
5. Marshmallow root
Marshmallow root is an herb that has a long
history of use as a treatment for coughs and sore throats. The herb can ease
irritation resulting from coughing because of its high mucilage content.
Mucilage is a thick, gluey substance that coats the throat.
One small study revealed that an
herbal cough syrup containing marshmallow root, along with thyme and ivy,
effectively relieved coughs resulting from common colds and respiratory tract
infections. After 12 days of taking the syrup, 90 percent of the participants rated
its effectiveness as good or very good.
Marshmallow root is also available as a
dried herb or a bagged tea. Add hot water to either and then drink it
immediately or allow it to cool first. The longer the marshmallow root steeps
in the water, the more mucilage will be in the drink.
Side effects can include stomach upset, but
it may be possible to counter this by drinking extra fluids.
6. Salt-water gargle
This simple remedy is one of the most
effective for treating a sore throat and wet cough. Salt water reduces phlegm
and mucus in the back of the throat which can lessen the need to cough.
Stir half a teaspoon of salt into a cup of
warm water until it dissolves. Allow the solution to cool slightly before using
it to gargle. Let the mixture sit at the back of the throat for a few moments
before spitting it out. Gargle with salt water several times each day until the
cough improves.
Avoid giving salt water to younger children
as they may not be able to gargle properly, and swallowing salt water can be
dangerous.
7.
Bromelain
Pineapples
contain bromelain, which may help to treat a cough.
Bromelain
is an enzyme that comes from pineapples. It is most plentiful in the core of
the fruit.
Bromelain
has anti-inflammatory properties and may also have mucolytic properties,
which means that it can break down mucus and remove it from the body.
Some
people drink pineapple juice daily to reduce mucus in the throat and suppress
coughing. However, there may not be enough bromelain in the juice to relieve
symptoms.
Bromelain
supplements are available and may be more effective at relieving a cough.
However, it is best to speak with a doctor before trying any new supplements.
It is
possible to be allergic to bromelain, and this herb can also cause side
effects and interact with medications. People who take blood thinners or
specific antibiotics should not take bromelain.
8.
Thyme
Thyme has
both culinary and medicinal uses and is a common remedy for a cough, a sore
throat, bronchitis, and digestive issues.
One study found
that a cough syrup consisting of thyme and ivy leaves relieved coughing more
effectively and more rapidly than a placebo syrup in
people with acute bronchitis. Antioxidants in the plant may be
responsible for its benefits.
To treat
coughs using thyme, look for a cough syrup that contains this herb.
Alternatively, make thyme tea by adding 2 tsp of dried thyme to a cup of hot
water. Steep for 10 minutes before straining and drinking.
9.
Dietary changes for acid reflux
Acid
reflux is a common cause of a cough. Avoiding foods that can trigger acid
reflux is one of the best ways to manage this condition and reduce the cough
that accompanies it.
Every
individual may have different reflux triggers that they need to avoid. People
who are unsure of what causes their reflux can begin by eliminating the most
common triggers from their diet and monitoring their symptoms.
The foods
and beverages that most commonly trigger acid reflux include:
·
alcohol
·
caffeine
·
chocolate
·
citrus
foods
·
fried and
fatty foods
·
garlic
and onions
·
mint
·
spices
and spicy foods
·
tomatoes
and tomato-based products
10.
Slippery elm
Native
Americans traditionally used slippery elm bark to treat coughing and
digestive issues. Slippery elm is similar to marshmallow root as it contains a
high level of mucilage, which helps to soothe a sore throat and cough.
Make
slippery elm tea by adding 1 tsp of the dried herb to a cup of hot water. Steep
for at least 10 minutes before drinking. It is important to note that slippery
elm can interfere with the absorption of medications.
11.
N-acetylcysteine (NAC)
NAC is a
supplement that comes from the amino acid L-cysteine. Taking a daily dose may
lessen the frequency and severity of a wet cough by reducing mucus in the
airways.
A
meta-analysis of 13 studies suggests that NAC can significantly and
consistently reduce symptoms in people with chronic bronchitis. Chronic
bronchitis is a prolonged inflammation of the airways that causes
mucus build-up, a cough, and other symptoms.
The
researchers suggest a daily dose of 600 milligrams (mg) of NAC for people
without airway obstruction, and up to 1,200 mg where there is an obstruction.
NAC can
have severe side effects, including hives, swelling, fever, and
difficulty breathing. Anyone considering this approach should speak to a doctor
first.
12.
Probiotics
Miso soup
is rich in probiotics.
Probiotics
do not directly relieve a cough, but they may boost the immune system by
balancing the bacteria in the gut.
A
superior immune system can help to fight off infections or allergens that may
be causing the cough.
One type
of probiotic, a bacteria called Lactobacillus,
provides a modest benefit in preventing the common cold, according to research.
Supplements
containing Lactobacillus and
other probiotics are available at health stores and drug stores.
Some
foods are also naturally rich in probiotics, including:
·
miso soup
·
natural
yogurt
·
kimchi
·
sauerkraut
However,
the number and diversity of probiotic units in foods can vary greatly. It may
be best to take probiotic supplements in addition to eating probiotic-rich
foods.
Tips to
help prevent a cold
It is not
always possible to avoid getting a cough, but the following tips can reduce the
risk:
·
Avoiding contact with people who are sick: Maintain a safe distance from
people who have a head cold, flu, or a cough.
·
Washing hands regularly: Use soap and warm water to remove
bacteria and viruses from the skin. Teach children how to wash their hands
properly. Use an alcohol-based hand sanitizer outside the home when necessary.
·
Using disinfectant: When a family member is ill, clean the kitchen
and bathroom regularly with a disinfectant. Wash bedding, towels, and soft toys
on a hot wash.
·
Staying hydrated: Drink enough water, herbal teas, and other
beverages to avoid dehydration.
·
Reducing stress: Stress affects the immune system and increases
the risk of getting sick. To alleviate stress, a person can exercise
regularly, meditate, do deep breathing, and try progressive muscle relaxation
techniques.
·
Getting enough sleep: Aim to sleep for 7–9 hours each night to stay fit
and healthy.
·
Taking immune-boosting supplements: Consider taking zinc, vitamin C,
and probiotics during cold and flu season to keep illness at bay.
Allergy
symptoms can sometimes mimic those of a cold. Reduce allergy flare-ups by
avoiding triggers such as pollen, dust mites, animal dander, and mold. See a
doctor about getting allergy shots or medications.
