by Andreea Laza

If you are looking for the highest natural sources of quinine, continue reading this article and find out what they are. But first.

Quinine is the predecessor of chloroquine. In other words, quinine is one of the natural alternatives to hydroxychloroquine. But before we get into the highest natural sources of quinine, let’s see what quinine really is.

3 Highest Natural Sources of Quinine

What Is Quinine?

Quinine is one of the oldest and best natural treatments for malaria. The Jesuit missionaries discovered the antimalarial properties of quinine in the 17th century and prepared the drug, which was then called the “bark of the Jesuits.” Studies have shown that its successor chloroquine, respectively hydroxychloroquine can have great results against malaria.

Thus, we want to share with you the 3 highest natural sources of quinine for this purpose. Without further ado, here are the best natural sources of quinine, supplements that have the highest quantity of quinine in them.

What Are The Highest Natural Sources of Quinine?

3 Highest Natural Sources of Quinine - Chincona Bark
Cinchona tree leaf (Jesuit’s bark)

1. Cinchona Tree Bark

Quinine is a natural extract from the Cinchona trees family. The bark of this tree is one of the highest natural sources of quinine in the world. The quinine tree (Cinchona succiruba) is native to South America and can reach heights of over 20 meters.

It has long, elliptical leaves, reddish on the inside, and bright pink flowers. The outer layer of the bark is brown-gray, and the inner layer is reddish-brown. For therapeutic purposes, the bark is harvested in autumn, from trees of at least 6 years old. Once dried, the bark is ground and used in the preparation of tinctures, dry extracts, decoctions, and medicinal wine. You can even find it in capsules.

Quinine extract is also used in the alcoholic beverages industry (bitters) and soft drinks (tonic water). So when you think quinine, think bitter. Cinchona tree bark is one of the highest natural sources of quinine out there.

2. Tonic Water

Tonic water is one of the most available and highest natural sources of quinine. Opt for a clean label tonic water that doesn’t come loaded with preservatives, sugars, or harmful sugar substitutes. While the content of quinine in tonic waters is generally low, if drunk regularly, tonic waters can act as great prevention. You can also make your own tonic water at home, following this recipe:

  • 3 cups of water
  • ¼ cup of lemon juice
  • 1/2 tsp cinchona extract
  • the peel from 3 limes cubed
  • the peel from 3 lemons cubed
  • the peel from 2 oranges cubed
  • 3 cardamom pods
  • 1 tablespoon dried lavender flowers
  • ¼ teaspoon kosher salt

Combine the ingredients together in a jar. Seal and give it a good shake. Store the jar in the fridge for the next 72 hours, and shake daily. Sweeten with date syrup, raw honey, or coconut sugar to taste and your tonic water is done.

3. Grapefruit

Grapefruit contains quinine-like substances, which in turn are effective in treating malaria. The explanation comes from the fact that grapefruit peel is loaded with a powerful essential oil called limonene. Limonene is known for its antiplasmodial activity, which makes it a powerful natural alternative to antimalarial drugs, including quinine.

To enjoy the healing benefits of the essential oils in grapefruit peel, heat up one grapefruit in the oven for a couple of minutes and eat its pulp (don’t microwave!). Or, steam grapefruit peel on a double boiler (bain-marie) and then eat it as is. Beware! Use organically grown grapefruit because pesticides gather in the peel of citrus fruits.

Indulge in freshly squeezed grapefruit and orange juice daily. Make the juice even more powerful by adding fresh ginger and turmeric powder to the mix. This citrus juice is not only a great barrier against viruses but also an immune system booster against any disease. Have plenty of grapefruits and fresh grapefruit juice on a daily basis.

I saw a recipe for a “virus” treatment.
Peel of 3 grapefruit and 3 lemons
Boil for 2 hours in a pan with a tightly fitting lid in water 3cm above the level of the peelings.
Take 1 tbsp 3 times a day till symptoms resolve.

As per instructions on the internet, I peeled 2 grapefruits and 2 lemons, cut the peels into slightly smaller pieces, brought them to a quick boil for a second, then simmered them in a pot with a glass top for 2 hours, making sure the steam did not get vented. After removing from the heat and cooling for 2 hours, I took a tablespoon full and drank it, and I’ll be darned it tasted just like quinine!!! You guys are geniuses! My wife and I are using it for the prophylactic effect. Long live the People. Long live the quinine.

Hi, Holly! You don’t need that high temperatures to heat up the grapefruit peels, simply heat it up in a pan with a little water. Use organic grapefruit if possible, because the conventional grown ones are sprayed with chemicals and the peel stores that toxic waste. Much health to you! 💚

Hello Marie! Personally, I don’t recommend Indian tonic water as a natural treatment for fever. Fever is the body’s way to signal inflammation (viral or bacterial), hence it is not the problem per se (when it’s not very high), but a natural mechanism to bring our attention that there’s something going on in the body, that our immune system is fighting against. Please consult a medical doctor. Much health to you! 💚

Even organic citrus is waxed with “food grade” petroleum (there is no such thing really), so you have to boil water throw in the fruit for a minute then run under cold water and brush off the wax with a clean natural bristle brush and rinse.

Hello Liana! Yes, even organic fruits need a good wash. You can also put them in a sink filled with water and pour apple cider vinegar or baking soda and leave them to stay for a few minutes, then rinse well and you can use them. Thank you for your input. 💚

Hi Jessica and thank you for your kind words, we really appreciate. If you refer to the tonic water recipe, ideally you should consume it over the course of a few days, while keeping it in the fridge. It is a small batch, so I don’t think it can last for too long, but if you want to make a larger quantity at once, the best thing to do is store it in the fridge in glass bottles, or in the freezer (in this case don’t fill the bottle all the way up). Much health to you!💚

`Hello – not everyone can get grapefruit year round on demand. I am wondering about preserving grapefruit peels, so that i may steep them as needed. Which preserves the active ingredients in the peels the best –
1. peeling them and freezing the peels? (in this case, does the pith have any of the important essences needed?)
2. Drying the grapefruit peels after taking them off the fruit.

I can preserve the fruit in other ways, but I’m wondering if drying the peels will make them lose their essential oils and other properties that are needed?

I was also considering a vodka extraction tincture, but that would render the peels unusable for awhile right, until the extraction would be complete?

Reply

Andreea Laza November 6, 2021 - 10:25

Hi, Elle! The best ways to preserve grapefruit peels are exactly these two, freezing them or drying/dehydrating them. Either way, they don’t lose the essential oils in them for future use. If you want to dehydrate them in a dehydrator, use a temperature of 40°C(104°F) maximum. This will not make the peels lose their essential oils. Alcohol extraction takes some time for the tincture to be ready, and you can not use it right away, this is true, but this is another useful preserving method (tincture/extraction). I hope I helped, much health to you! 💚

Does pomelo have similar properties as grapefruit?

Reply

Hi, Sean! Pomelo is the ancestor of the grapefruit, which is a backcross between pomelo and sweet orange. The essential oils in pomelo peel have antimicrobial and antibacterial properties, and is especially effective against strep bacteria, which is why it have been traditionally used in parts of South Asia to soothe a cough or a sore throat. I personally believe that you can use pomelo peel, the bitter kind, instead of grepfruit peel if you don’t have the later available. Much health to you! 💚

Thank you for this article. I made our first batch in August, put it in glass bottles and store it in a backup fridge we hardly open and keep one jar in the house fridge. I sweetened it with a little raw local honey and we each take 2 tab. every morning in our tea. We’re 72 & 74. We only wear masks if in a health care facility, we go about our lives surrounded by people and as of now, not even a cold in over 4 years. We know we could get sick, we take on that responsibility, and we are healthy. We eat organic 90% of the time. Yes my husband has Altzeimers, I have arthritis in knees and fingers and neck, other than that we are healthy. I take a prescript for glaucoma, my hubby one for gout. We refuse to take any other prescripts and our PA has finally accepted our decisions. Thank you for your weekly newsletter, I am always looking for natural ways of living our lives.

Hi, Tracy! I’m really happy you’ve found our article informative, and I hope this information will serve you as well as your clients. We don’t sell any products on this website, hence we do not set the prices for the products we recommend. As for the price of this tonic water, it’s the same with the more popular Fever-Tree, but the difference is that the tonic water from Q is sweetened with agave nectar instead of sugar, and I’m guessing as a Master Herbalist, you know how damaging sugar is for our health. In addition, we included a recipe for tonic water so that anyone can make at home and not have to buy any tonic waters on the market. I sure hope you take advantage of all this free information and use it wisely. Much love!

Could you please advise what is the purpose of lemons in the 3 grapefruit 3 lemon recipe?
I am unable to find any information about lemon containing Quinine. Lemons are easier to obtain than grapefruit, so if lemons do contain Q, we could just use lemons. However if lemons do not contain Q, why are lemons included in the mix with grapefruit?

Reply
Andreea Laza
Andreea Laza January 28, 2022 - 14:22

Hi Andy! Lemons, as well as grapefruits and most citrus fruits, contain in their peels essential oils, and one of the components in these essential oils is limonene, which has the ability to stop the development of the malaria-causing parasite and kill it, similar to quinine. This is why the tonic water recipe makes use of cubed citrus peels because they release their essential oils into the tonic water. So yes, you can use lemon peels too to make the tonic water, if you don’t have grapefruit around. It’s more important to use organic citrus fruits, than what citrus fruits you use, because pesticides build up in their peel. Let me know if you have other questions, and I will be happy to answer. Much health to you!
