Can Pineapple Juice Relieve a Cough? Benefits of Pineapple

Coughing is the body’s natural reflex to clear irritants from the airways. While it serves an important function, persistent coughing can be extremely disruptive and unpleasant.

When traditional cough syrups and medications fail to provide relief, many seek natural alternatives. One such remedy that has garnered attention is pineapple juice.

But can pineapple juice effectively relieve cough symptoms? Let’s explore the science and evidence behind using pineapple as a cough treatment.

I. How Pineapple Juice May Alleviate Coughs

Pineapple contains an enzyme called bromelain that possesses anti-inflammatory and mucus-dissolving properties.

Some studies have found bromelain effective in treating respiratory issues like bronchitis, sinusitis, asthma, coughs and colds.

Researchers suggest that bromelain’s ability to break down proteins contributes to its efficacy in dissolving mucus and suppressing coughs.

In addition to bromelain, pineapple juice offers numerous other nutrients and vitamins that can potentially help relieve coughs. These include:

  • Vitamin C: Strengthens the immune system and combats infections.
  • Copper: Has anti-inflammatory effects that may reduce coughing.
  • Magnesium: Relaxes bronchial smooth muscles to open airways.
  • Manganese: An antioxidant that protects lung tissue from inflammation.

While anecdotal evidence points to the potential cough-relief benefits of pineapple juice, more concrete scientific research is still needed. However, its rich nutritional profile and anti-inflammatory properties do hold promise for natural cough treatment.

II. How to Use Pineapple Juice for Treating Coughs

There are several ways to harness the therapeutic potential of pineapple juice for cough relief:

1. Pineapple Juice, Honey, Salt, Pepper

A simple but popular home remedy combines 1 cup pineapple juice with 1-2 tbsp honey and a pinch each of salt and pepper.

The mixture of sweet and spicy flavors helps soothe the throat. Honey and pineapple juice contain antioxidants that fight infections causing coughs.

Drink this concoction warm, in 1⁄4 cup servings, 2-3 times daily.

2. Pineapple, Ginger and Honey

For a zesty cough treatment, blend 1 cup pineapple juice with 1 tsp grated ginger, 1 tbsp honey, 1⁄4 tsp cayenne pepper and 1⁄4 tsp salt.

Ginger’s antimicrobial properties combat cough-triggering germs.

Cayenne thins mucus, while honey and pineapple juice relieve sore throats. Drink 1⁄4 cup of this spicy mixture 2-3 times a day.

3. Strawberry Pineapple Popsicles

For a refreshing remedy, blend 3⁄4 cup pineapple juice with 1 cup chopped strawberries. Freeze the mixture in popsicle molds.

The soothing coldness can alleviate coughs and sore throats. Strawberries provide a boost of immune-strengthening vitamin C.

4. Pineapple Tea

Steep 2 pineapple tea bags in 1 cup hot water for 5 minutes. Remove tea bags and stir in 1-2 tsp honey.

The warmth of the tea can relieve throat discomfort.

Consume this soothing tea 2-3 times a day. Caffeine-free pineapple tea is safe for children.

III. What Causes Coughing?

To treat a cough effectively, it helps to understand what’s triggering it in the first place. Common causes of coughs include:

  • Respiratory Infections: Colds, flu, bronchitis, pneumonia, or sinusitis from viruses or bacteria.
  • Allergies: Inhaled irritants like pollen, dust mites, pet dander.
  • Asthma: The airways become narrowed or inflamed.
  • GERD: Acid reflux irritates the throat and triggers coughing.
  • Smoking: Chemical irritants in cigarettes induce coughs.
  • Medications: ACE inhibitors used for blood pressure can cause dry coughs.
  • Weather Changes: Dry, cold air can irritate airways.
  • Viral Infections: Measles, croup, or whooping cough.

Identifying the root cause of your cough allows for targeted treatment. Pineapple juice could help relieve coughs resulting from colds, allergies, or throat irritants. However medical advice is crucial for managing chronic issues like asthma, acid reflux, or infections.

IV. Other Home Remedies for Coughs & Colds

While pineapple juice is emerging as a potential cough treatment, other natural remedies have been traditionally used to alleviate cough and cold symptoms:

1. Honey and Lemon

A simple home remedy combines 1 tbsp honey and juice from 1⁄2 lemon in a cup of warm water. The honey coats and soothes the throat, while vitamin C-rich lemon boosts immunity.

Drink this mix 2-3 times a day to reduce coughing. Keeping hydrated also thins out mucus.

2. Saltwater Gargle

Gargling with warm salt water can relieve coughs caused by throat irritations. Dissolve 1⁄2 tsp of salt in a cup of warm water.

Gargle this solution for 30 seconds, 2-3 times daily to coat the throat and draw out excess mucus. The salt has antibacterial effects.

3. Turmeric Milk

Turmeric contains the compound curcumin which has antioxidant and anti-inflammatory benefits. Mix 1⁄2 tsp turmeric powder into a warm cup of milk.

The soothing, medicinal drink provides relief from coughing and associated chest congestion. Drink once or twice daily.

4. Ginger Tea

Ginger’s antimicrobial properties make it effective against cough-causing pathogens. Steep freshly grated ginger in hot water and sip slowly.

The spicy warmth clears congestion, soothes the throat, and suppresses the urge to cough. Drink 2-3 cups of ginger tea daily.

5. Chicken Soup

Warm, steamy chicken soup can break down mucus secretions that trigger coughing. Soup also provides hydration and nutrients helpful for combating infections that cause coughs.

Have a bowl of homemade chicken soup everyday when cough symptoms flare up.

V. The Benefits of Pineapple for Coughs & Colds

Beyond being a delicious tropical fruit, pineapples offer specific beneficial properties that can help relieve cough and cold symptoms:

1. Vitamin C

Pineapples are an abundant source of immune-boosting vitamin C. Getting enough vitamin C is key to warding off cough-inducing viruses and bacteria.

Just one cup of pineapple chunks provides 78.9 mg of vitamin C, exceeding the daily recommended intake.

2. Bromelain

This unique anti-inflammatory enzyme in pineapples can suppress coughs by breaking up and thinning mucus secretions in the throat and lungs.

Bromelain also enhances the absorption of medications, allowing them to work faster against coughs.

3. Manganese

Pineapples are one of the richest sources of the mineral manganese which has antioxidant properties that protect the lungs against inflammation and damage from infections.

Manganese also strengthens immunity to help the body overcome cough-causing pathogens.

The combination of all these beneficial compounds makes pineapple a potential powerhouse for keeping coughs and colds at bay.

While not a cure-all, pineapple juice could be a handy item to stock in your medicine cabinet during the cold season.

VI. FAQs About Pineapple Juice for Cough

1. What foods should you avoid during a cough?

Dairy products, greasy fast foods, spicy cuisine, and citrus fruits can irritate the throat and worsen cough symptoms.

Opt for soft, soothing foods like soups, broths, mashed potatoes, and cooked cereals instead.

2. What’s the fastest way to cure a cough?

Unfortunately, there’s no instant fix for coughs. While home remedies can provide temporary relief, the only way to truly cure a cough is to treat the underlying cause, whether it’s an infection, allergy or irritation.

Seeking medical advice for chronic coughs lasting over 2 weeks is recommended.

3. What can cause a cough?

Coughs can arise from an array of conditions including colds, flu, allergies, asthma, smoking, acid reflux, respiratory infections, weather changes, medications, viral infections and more.

Identifying and addressing the root cause is key to stopping your cough.


While the science behind pineapple juice as a universal cough remedy remains inconclusive, its vitamin C, bromelain, and manganese content do possess therapeutic potential.

When combined with other natural treatments like honey, lemon, and ginger, pineapple juice could offer some relief, especially for coughs resulting from colds or throat irritations.

However, severe, chronic, or worsening coughs warrant medical advice. Maintaining good preventive health habits like hand hygiene, hydration, and diet can help thwart coughs and keep your airways clear.
