The Benefits of Lionberry

Elderberry Phytochemicals Work in Our Bodies

  • Cancer Health: Elderberries contain anthocyanins that may reduce the risk of cancer and stop colon cancer cells from growing by up to 60%.

  • Blood Sugar Health: Elderberry may help prevent diabetes by fighting insulin resistance, lowering blood glucose levels, and reducing inflammation.

  • Gut Health: Elderberries are high in fiber, which may help promote gut health.

  • Skin Health: Elderberries contain antioxidants that may help protect skin from pollution, smoke, and UV radiation.

Elderberry Plant Benefits Protect Us From The Crowd

  • Immune Health: Elderberry contains anthocyanins, which can attach to viral glycoproteins and prevent viruses from entering host cells. Elderberry extracts have shown inhibitory effects on Influenza A, B, and H1N1 viruses.

  • Suppress Viruses: Elderberry contains high amounts of polyphenolic compounds, such as flavanols, phenolic acids, and anthocyanins. These polyphenols can suppress the activity of viruses and bacteria.

  • Immune Boosting: Elderberry contains acid polysaccharides, such as pectins, which may boost immune function by stimulating macrophages.

Elderberry Juice Might Speed Up Thinking in Elderly People With Early Dementia (Musich et al., 2025; RL 7

What people eat can affect their brain health. Scientists know that eating plants with certain natural chemicals can help with memory. In this study, they wanted to see if these chemicals can help older people with early dementia. They compared juice from American elderberry and a flavor drink that tasted the same. 

Twenty-four elderly people with very mild dementia took part in the study. They took tests, such as word puzzles, to measure how mentally sharp they were. Then, three times a day for 6 months, they took a teaspoon of juice. Some people took elderberry juice the whole time. Others took the flavor drink. Which juice each person took was kept secret until the end of the study. At 3 months and again at 6 months, the elderly people took the thinking tests again. Between the beginning and end of the study, scientists compared test results. 

Thinking seemed to speed up slightly in the group of people who took the elderberry juice. It did not speed up in the group who took the flavor drink. 

The study was small and scientists are still not certain that the juice helped. But the results were promising. Bigger studies should help us understand how American elderberry juice might affect brain health.

 
 
Natural Substances in American Elderberries Protected Mice From Stroke Injury (Banji et al., 2022; RL 9)

Scientists are studying the brain health benefits of natural chemicals called anthocyanins. Anthocyanins occur in some plant foods, including colorful berries like elderberries. They fight inflammation in the body. Inflammation is a complex immune response meant to protect the body, but it can also harm the body. Some brain disorders occur with inflammation, such as Alzheimer’s. Inflammation can also play a role in depression, anxiety, and bipolar disorder.

After mice eat anthocyanins, they show up in the bloodstream within 20 minutes. Likely a similar thing happens in humans. Some also travel down the gut, where they may nourish the good bacteria living there. Anthocyanins also wind up in the liver, heart, kidney, and brain. Their ability to cross from the blood into the brain surprised some scientists. The brain has a protective barrier to keep out many chemicals. In the brain, anthocyanins interfere with inflammation in a number of ways.

In one study, scientists added inflammatory chemicals to mouse brain immune cells. As expected, the cells erupted with an inflammatory response. Then they tried again after first adding American elderberry extract. This time, the cells’ inflammatory response was mostly blocked. The scientists believe this was due to anthocyanins in the elderberry.

Other experiments have found possible protective effects of anthocyanins. These experiments looked at anthocyanins in other plants. Benefits occurred in animal studies of alcohol, high-fat diets, and Huntington’s disease. In humans, benefits have been seen in studies of early dementia.

Much science remains to be done on anthocyanins. We do not know enough about the right dose for human beings, nor how much might be too much. Anthocyanins might interact with medications in ways we don’t yet understand. And they might affect different people differently.

 
 
American Elderberry May Protect Brain from Stroke Damage (Banji et al., 2022; RL 8)

Scientists tested whether two plant extracts could protect against brain damage from stroke. They tested elderberry and an African plant called Sutherlandia. Groups of mice eating normal diets were compared for two months. Some had dried Sutherlandia powder added to their food. Others had dried American elderberry powder added to their food. Still others ate a normal diet with no supplements. 

Under anesthesia, all the mice had surgery. In most of the groups, scientists interrupted, then restored blood flow to the brain, like a stroke. For comparison, some mice had surgery without the stroke. 

When the mice woke up, scientists tested their coordination. They also examined the mice’s brains. Among mice that had strokes, those that had eaten the plant powders were more coordinated. Their brains also showed less damage. Mice that had not eaten the powders were less coordinated and had more damage. 

Scientists know oxidation and inflammation can hurt the brain after stroke. In mice, eating these plants before stroke seemed to cut down on this type of brain damage. American elderberry can reduce brain damage from stroke in mice. It’s worth exploring whether the plant could help humans in this way too.

American Elderberry Extracts Inhibit Brain Tumor Cells In Lab (Lamy et al., 2018; RL 8)

Glial cells protect and nourish nerve cells. Glioma is a type of brain cancer that happens when glial cells divide, get out of control, and form a mass (a tumor). 

Like healthy parts of the body, a tumor needs a blood supply, because blood delivers oxygen. These tumors direct the body to create new blood vessels. As gliomas grow, their new blood vessels do a spotty job delivering oxygen. This lack of oxygen turns on genes, or instructions inside the cells, that make the glioma harder to treat. 

American elderberry contains natural health-giving chemicals. In this study, researchers wanted to build on a 2006 study that found elderberry may fight cancer. They used extracts from elderberry and elderflower. They also lined up individual chemicals derived from elderberry, plus a chemical mix. They wanted to see how each of these affected glioma cells and blood vessel cells.

In containers, they bathed glioma cells in extracts, individual chemicals, or the mix. To simulate what happens in real tumors, they reduced oxygen supply to some cells. 

The extracts, especially the berry ones, reduced some glioma cells’ tendency to divide. This was true both when normal and low amounts of oxygen were present. Individual chemicals also did this. They worked better as a mix than on their own. Berry extracts revved up self-destruction in blood vessel cells and some glioma cells. 

These results add to evidence that elderberry might inhibit cancers.

A government ministry and a university in Quebec, Canada funded the study. The researchers declared they had no financial conflicts of interest.

 
American Elderberries Have Anti-Cancer Properties (Thole et al., 2006RL 9)

Elderberries contain natural health-giving chemicals. These chemicals can fight cancer, boost the immune system, and weaken flu virus. European elderberry has been bred for many years as a medicinal plant. It is used in some popular drugstore medicines. American elderberry is more wild, but it too has been traditionally used for medicine. In this study, scientists compared both kinds of elderberry for their cancer-fighting powers. They used chemistry to isolate natural chemicals from each type of berry. Then they ran tests on the chemicals. Both elderberry types proved able to combat cancer processes in these lab tests.

Elderberry Might Help With Blood Sugar and Fat Burning (Teets et al., 2024; RL 8)

Some scientists suspect healthful chemicals in berries may help people control their weight. The chemicals might help by nourishing the beneficial bacteria living in our intestines. 

Scientists asked overweight people to participate in a study using American elderberry juice. In this study, 18 people spent one week drinking either elderberry juice or an imitation. Then each person switched over to the other drink for one week. During the study, the participants ate a controlled diet and gave samples of blood and poop. Scientists checked blood sugar and studied bacteria in the poop. 

After the period of drinking elderberry juice, people’s bodies changed. They had slightly more healthful bacteria in their poop. Their blood sugar was better. And fat burning increased. These changes did not occur after the imitation drink. This study suggests American elderberry might help with gut health and weight management. Still, this was a small, brief study, so the results aren’t definitive. Longer studies with more people will help give a clearer picture.

Unlike European Elderberries, American Elderberries Lack Certain Toxic Chemicals (Appenteng et al., 2021RL 9)

Some plants naturally contain small amounts of chemicals that can turn into poison. These chemicals help protect the plants from disease and from being eaten. Elderberries in Europe have some of these chemicals, which can turn into cyanide in the body. So these chemicals have to be destroyed to make healthy drinks, foods, or supplements. This may be done by heating, which could destroy healthful chemicals in elderberries. 

Scientists checked to see if American elderberries also contain these chemicals. They tested store-bought American elderberry juice. They also tested seeds, skin, pulp, stems, juice, and berries from the American plant. 

Store-bought juice had none of the chemicals. Small amounts were in the fresh plant parts, especially in stems and unripe berries. But levels were too low to be harmful, and they were much lower than even the harmless levels in fresh apple juice. 

Products made from American elderberry may not need as much processing.

Does Freezing Affect Elderberry Anthocyanin Levels? (Johnson et al., 2016; RL 9)

American elderberries have beneficial chemicals called anthocyanins and polyphenols. Freezing is a useful way to preserve fresh elderberries. But it hasn’t been clear how freezing affects the anthocyanins and polyphenols.

The scientists planted three different types of American elderberry. They harvested ripe berries, deep-froze them for one week, thawed them, and made juice. They measured levels of the two chemical types in the juice. Then the scientists froze juice samples. They thawed and tested the juices again after 3 months, 6 months, and 9 months in the freezer.

They found that anthocyanin and polyphenol levels differed among the cultivars’ fresh juice. Bob Gordon had the highest levels of both.

For polyphenols, all three lost some in the first three months of storage, then losses leveled off. At the 9-month mark, all three had at least 72% of their original amounts of polyphenol.

As for anthocyanins, the scientists checked two types: monomeric and individual anthocyanins.

For monomeric anthocyanins, all three cultivars lost large amounts during frozen storage. Bob Gordon had the highest levels by far after 9 months—about 58% of what it started with. Wyldewood had 28% and Adams II had 18% of their initial anthocyanins after 9 months.

Individual anthocyanins were less stable than monomeric during frozen storage. For all three cultivars, individual anthocyanins were almost gone by 9 months.

United States government agencies funded this study.

European Elderberry Killed Flu But Not Covid Virus In A Lab (Eggers M. et al., 2022; RL 7)

Viruses that infect the lungs often spread down from the nose, mouth, and throat. Gargling with rinses or with certain natural products may cut down on virus spread. That could reduce sickness and the spread of sickness.

In this study, researchers tested several plant-based liquids in a lab. They wanted to see how well these liquids do at killing viruses. In other words, they studied the liquids’ ability to be virucidal. They tested green tea, chokecherry juice, elderberry juice, and pomegranate juice. They tested flu virus and SARS-CoV-2, plus a tough virus called MVA.

Each juice or tea was mixed in a container with virus. Then the scientists checked to see how much virus had died off.

Of all the liquids, chokeberry juice was the strongest virucide. It reduced flu virus and SARS-CoV-2 by over 99% in 5 minutes. Chokeberry also knocked back MVA by 96% in 1 minute.

All four liquids reduced influenza virus by over 99% in 5 minutes. Pomegranate juice and green tea cut SARS-CoV-2 by about 80% in 1 minute. But elderberry juice did not significantly kill SARS-CoV-2 in this study.

All scientific studies have limitations. In this study, humans didn’t gargle with the liquids. That’s important because how a substance interacts with viruses in a dish or test tube may differ in people. The scientists added vitamin C to the green tea, though that is not how people usually make it. All the juices were prepared with heating (pasteurization). Heating juice, while it kills harmful germs in the juice, might also change its properties. The elderberry juice in this study came from a German supplier. American elderberries might work differently.

A nonprofit called German Cancer Aid paid for the study. Two of the researchers are partners in a company that makes dietary supplements.

 
Elderberry Shifted the Immune System’s Response to Viruses (Schön et al., 2021; RL 8

Scientists studied natural plant chemicals in a commercial elderberry product called Eldosamb. This powdered extract contains health-giving chemicals called anthocyanins. The scientists wanted to learn how the extract interacts with the immune system.

In one part of the experiment, the scientists studied if elderberry could kill a virus called MVA. (The MVA virus has some similarities to coronavirus and flu virus but it is safer to study.) First the scientists infected cow cells with the virus. Then they mixed elderberry in with some containers of cells and not others. Finally they measured virus amounts in the two types of containers and compared. The elderberry strongly reduced virus amounts. It also reduced the virus’s power to infect new cells.

For the other part of the experiment, ten volunteers donated blood. In test tubes, the scientists mixed elderberry powder into the blood. They measured which immune chemicals the blood cells released in response to elderberry. These immune chemicals determine which path the body takes to fight off infection.

They found that elderberry steers immune cells down a path called the TH2 response. In the TH2 path, the body makes antibodies to fight viruses. The TH2 path also hits the brakes on inflammation. (The other path, the TH1 immune response, revs up inflammation. Inflammation can fight cancer cells and some types of germs. But it can be harmful if it goes haywire or lasts too long.) Elderberry can shift the immune response in a way that could be beneficial. 

 
Elderberry Protected Laboratory Cells from Influenza (Roschek et al., 2009; RL 8)

Every plant, including elderberry, contains a mix of natural plant chemicals or compounds. In a dish, scientists mixed an elderberry extract with a strain of flu called H1N1. They found that, in high doses, the extract kept the flu from infecting dog cells in the dish. Normally these cells are sensitive to flu virus. Studying the extract, the scientists found two compounds with anti-viral powers. These compounds, called flavonoids, bind to the virus. This prevents them entering the cells. It’s a little like putting boxing gloves on the hands of a lock-picker. One of the compounds, given on its own, was about as powerful as the anti-viral drug Tamiflu.

This study was not the last word on anti-viral properties of elderberry. Compounds can behave differently in a plant extract than in isolation. They can also behave differently in living beings compared to cells in a dish. But it encouraged scientists to continue studying elderberry.

The Dark Berry

Lionberry 's Weekly Delusion and Re-illusion Update.

BS Weekly #13

The color is not a coincidence.

The dark, almost-black purple of elderberry is not just a visual marker of ripeness. It is a signal of bioactive density. The anthocyanin molecule responsible for that color... cyanidin-3-glucoside, or C3G... is pH-responsive, meaning its molecular structure physically shifts depending on the acidity of its environment [12]. In acidic conditions it appears red. At neutral pH it goes purple. In alkaline conditions it shifts toward blue and eventually breaks down entirely [12]. This is not a cosmetic property. It is a window into the molecule’s chemistry. The same pH sensitivity that makes the color shift is what makes C3G reactive inside your digestive system... and reactive in exactly the right way, because your stomach is acidic, and acid stabilizes the molecule right when it needs to survive [14].

What C3G Actually Is

Cyanidin-3-O-glucoside... abbreviated C3G... is an anthocyanin. Anthocyanins are water-soluble plant pigments in the flavonoid family responsible for the red, purple, and blue colors of dark berries. Elderberry is one of the densest sources of anthocyanins in the known food supply.

C3G is specifically a cyanidin molecule with a glucose molecule attached at the 3-position of its carbon ring. That structure matters for how it moves through your body and how it interacts with your gut. C3G is not a GLP-1 agonist. It does not bind to the GLP-1 receptor the way tirzepatide, Mounjaro, or Zepbound do. What it does is different and arguably more interesting... it stimulates your intestinal L cells to make more of your own GLP-1 from the inside [1]. The drug mimics the hormone from the outside. Elderberry... because it is food, because it is a berry, because it moves through your gut the way food does... triggers your body to produce the hormone itself. That is not a drug mechanism. That is food doing what food has always done. We just finally have the tools to watch it happen.

Research published in npj Science of Food confirmed that C3G treatment increased GLP-1 secretion in intestinal L cells via the PPARβ/δ... β-catenin... TCF-4 signaling pathway, which enhances the transcription of the proglucagon precursor that L cells use to synthesize GLP-1 [1]. C3G stimulates GLP-1 secretion from intestinal L cells via this pathway, thereby enhancing insulin secretion and improving glycemic control [1].

What the L Cell Is and What GLP-1 Does to Your Body

The L cell is a specialized enteroendocrine cell lining the wall of the intestine, concentrated in the ileum and colon. Its job is to sense what is coming through the gut... nutrients, fiber, certain plant compounds including C3G... and release hormonal signals in response [2]. GLP-1 is produced in intestinal L cells through posttranslational processing of the proglucagon gene and is released from the gut in response to nutrient ingestion [3].

Once C3G triggers the L cell and GLP-1 is secreted into circulation, it does multiple things simultaneously throughout the body that are directly relevant to blood sugar, metabolic health, and fat metabolism:

It tells the pancreas to release insulin in a glucose-dependent manner... meaning only when blood sugar is actually elevated, which is why it does not cause the hypoglycemic crashes that some diabetes medications do [3].

It blocks glucagon... the hormone that raises blood sugar... from being secreted by the pancreas, which further stabilizes blood glucose levels after meals [3].

It slows gastric emptying... food moves more slowly from the stomach into the small intestine... which flattens the blood sugar curve after eating, reduces postprandial glucose spikes, and extends the feeling of satiety [4].

It acts on GLP-1 receptors in the brainstem and hypothalamus to promote fullness and reduce appetite... GLP-1 has been shown to promote satiety and reduce both food and water intake [4].

It directly supports fat oxidation... the WSU clinical trial documented a 27% increase in fat oxidation at rest and during exercise in participants consuming elderberry juice for one week, consistent with the metabolic effects of increased endogenous GLP-1 activity [17].

The half-life of endogenous GLP-1 in circulation is approximately two minutes before it is degraded by the enzyme DPP-4 [4]. This is why pharmaceutical GLP-1 agonists are engineered to be DPP-4 resistant... they stay in the system far longer than your body’s own version. Elderberry does not extend the half-life. What it does is increase the rate of production... more signal from more L cells, more often, through food.

Is C3G Found More in American Elderberry

Both American elderberry (Sambucus canadensis) and European elderberry (Sambucus nigra) contain C3G. A USDA study comparing both species grown side by side found that both produce cyanidin-based anthocyanins as their dominant pigments, but with meaningfully different profiles [6]. In European elderberry, C3G makes up roughly 40 to 50% of total anthocyanins. In American elderberry, the dominant anthocyanins are acylated forms... meaning the cyanidin molecule has an additional organic acid group attached... making up approximately 65 to 70% of total anthocyanins, with C3G present but not dominant [15].

What matters for the L cell is not which species has the highest percentage of C3G on paper. What matters is how much active cyanidin-based compound arrives at the L cell intact after surviving processing, storage, and the journey through your gut. Acylated anthocyanins from American elderberry were more stable than cyanidin 3-sambubioside from European elderberry, with acylation improving both heat and light stability [6]. American elderberry’s acylated forms survive the journey better... and they break down in the gut into the same cyanidin-based compounds that stimulate L cell GLP-1 production [1].

Total anthocyanin content in American elderberry cultivars ranges from 85 to 385 mg per 100 grams depending on cultivar and growing conditions [7]. That nearly fourfold range is not a minor variation. It is the difference between a berry that moves the needle on L cell stimulation and one that does not. The Wyldewood and Bob Gordon cultivars are among the highest-anthocyanin American elderberry cultivars documented in the literature [16].

How C3G Gets to the L Cell

C3G faces a gauntlet between the berry and the L cell. Understanding that gauntlet explains why processing matters so much.

The stomach is actually C3G’s friend. The pH value of the stomach environment is generally 0.9 to 1.5. Anthocyanins are relatively stable at pH 2 or below and can be rapidly absorbed in the stomach, appearing in plasma within 30 minutes after ingestion. The acidity that protects the molecule in a well-processed elderberry product continues protecting it in the stomach. Some C3G absorbs directly through the stomach wall into circulation [9].

The challenge comes in the small intestine. Anthocyanins are destabilized by the neutral to slightly alkaline pH of the small intestine. As C3G moves from the acidic stomach into the small intestine the pH rises, the molecule becomes less stable, and some degrades. What survives is absorbed via the SGLT1 and GLUT2 glucose transporters in the intestinal wall [9]. Exposure to intestinal conditions leads to a decrease in C3G bioavailability by 40 to 50% overall [10].

What does not get absorbed intact continues to the colon where Bifidobacterium metabolizes it. Those metabolites stimulate L cells to produce more GLP-1 through the SCFA pathway... a second route to the same destination [11]. Two pathways. One berry. Both landing on the L cell.

How to Process Elderberry to Preserve C3G for the L Cell

This is where most of the commercial elderberry industry gets it wrong and most consumers have no way of knowing.

C3G is destroyed by heat, oxidation, light, and time. Heating elderberry at temperatures ranging from 212 to 302°F causes significant structural changes in anthocyanins, degrading both the bioactive compounds and their antioxidant activity [8]. Extended heat processing does not sterilize the medicine... it eliminates it.

Elderberry, with its softer peel structure, is more prone to anthocyanin degradation by heat than other berry fruits [8]. A blueberry or a grape can withstand certain processing conditions that will simply destroy elderberry anthocyanins.

What preserves C3G so it can actually reach the L cell:

  • Fresh pressing or cold pressing to juice immediately after harvest
  • Dropping the pH of the finished product acidifies the environment and stabilizes the C3G molecule structurally... the color shift from purple toward red confirms it is working [12]
  • Flash pasteurization at the lowest temperature and shortest time that achieves food safety requirements rather than extended boiling
  • Cold storage to minimize oxidative degradation
  • Processing as close to harvest as possible... anthocyanins degrade in the berry after picking even without heat

The color of the finished product tells you most of what you need to know. A deeply purple, almost black elderberry juice has retained its anthocyanins. A pale, brownish, or dull product has not. The color is not the brand. The color is the medicine. Trust the color.

METABOLIC RECOVERY

It starts with the dark berry.

Everything else follows from here.
