Quinine Benefits for Lungs and Immune Support: Natural Remedy Uses, Safety & Science-Backed Health Effects

Published on   Last Updated on  January 27, 2026

You may have heard of Hydroxychloroquine and its main active ingredient: quinine. Quinine is antiviral, antifungal, antibacterial, antiparasitic, antimicrobial, and anti-inflammatory.

You can buy this as medication, but instead, I like to use my home remedy from plants to avoid the downside of taking drugs and the added sugar in tonic water-type drink options.

Tonic water also contains quinine, but the amount is minimal and insufficient to have any significant therapeutic effect, at only 5 mg/L.

What Are The Uses & Benefits of Quinine?

  1. It helps your body fight off viruses & flu. Quinine has been used for 400 years to treat malaria, and more recently, the HIV/AIDS virus and COVID-19.
  2. Quinine reduces fevers by exerting an antipyretic effect, activating pro-inflammatory mediators that reduce high fevers.
  3. Quinine supports lung function. When quinine and chloroquine are inhaled (like when you steam your head to fight a cold or flu), these two compounds activate the taste receptor proteins, reducing vasoconstriction and allergic reactions in the lungs, therefore stopping the 'asthma'/vasoconstriction symptoms from arising. It's also useful to release phlegm and mucus from your lungs.
  4. Quinine reduces leg cramps. Another regular use of quinine has been to treat leg cramps caused by vascular spasms. For more than 50 years, quinine, quinidine, and hydroquinone have been used to prevent muscle cramps.
  5. Quinine supports weight loss. In a controlled study, quinine was used to help control weight loss and reduce appetite and cravings. This is because Ayurvedic and Chinese medicine indicate that anything bitter supports blood sugar and appetite regulation.
  6. Quinine improves digestion. The bitterness also supports healthy stomach acid levels, so your digestive system affects your mind and body, as you are what you absorb after all. Many people eat organic, follow a clean diet, and eat more plants, but their absorption is very poor. This is a significant issue in our clinics, particularly over the past five years, as stress levels and environmental toxins have risen. 

Supplements That Contain Quinine 

I love this ingredient so much that I also included it as a critical synergistic player in my Immune Restore Capsules, combined with zinc.

Combining zinc with quinine enables quinine to enter your cells more quickly, resulting in a faster effect. If you are not a fan of bitter foods, you can take our Immune Restore Capsules. These capsules were a godsend for me and many of my clients with COVID-19. They are safe for both adults and children.

I believe in quinine so much that I have included it in its natural bioavailable form from grapefruit in our Para Cleanse and Candida Gone Capsules. It is a powerful ingredient, and its bitterness leads many people to avoid it in their diet.

Quinine Tonic  A Home Remedy Recipe

Ingredients

You need three rinds of lemons, three rinds of grapefruits, filtered water and Manuka honey.

Method 

Take the rinds of the lemons and grapefruits and cover with filtered water, about 3 inches above the peels. Bring to the boil & then simmer for 2 hours with a lid on. Use a stainless steel pot and a glass lid if possible. Never use nonstick or aluminium cookware, as they are highly toxic. 

  • Let this simmer for 2 hours, and do not remove the lid until it has cooled completely. You don't want the quinine to escape in the steam.
  • Sweeten with Manuka honey to taste, as it will be bitter. You only take a tablespoon at a time, so you don't need to drink glasses of it.

Take 1 tbsp every few hours if you have a viral infection, cold, or flu.

Take 1 tbsp before meals if you have joint pain, leg cramps, lung or digestive issues or are trying to lose weight.

Discontinue as you feel better or reach your goals, and use it as a home remedy you can mix whenever needed.
