Elderberry, a fruit known for its potential health benefits, has become a popular ingredient in supplements and remedies. But amidst its rise in popularity, concerns about its safety and potential toxicity often arise. Can elderberry truly be toxic? The answer is complex, and understanding the nuances is crucial before incorporating elderberry into your wellness routine.
Understanding Elderberry: Species and Forms
Elderberry refers to various species of the Sambucus genus, with Sambucus nigra (European elderberry) being the most widely used and studied for its medicinal properties. Other species, such as Sambucus canadensis (American elderberry), are also used, but their chemical composition may vary slightly.
Elderberries are available in various forms, including:
- Raw berries
- Cooked berries
- Elderberry juice
- Elderberry syrup
- Elderberry supplements (capsules, tablets, lozenges)
- Elderflower preparations
The form in which elderberry is consumed significantly impacts its safety profile.
The Source of Toxicity: Cyanogenic Glycosides
The primary concern regarding elderberry toxicity stems from the presence of cyanogenic glycosides. These naturally occurring compounds are found in various plants, including elderberry. When ingested, cyanogenic glycosides can be broken down in the body to release hydrogen cyanide (HCN), a toxic substance that interferes with cellular respiration.
The concentration of cyanogenic glycosides varies depending on the specific part of the elderberry plant. While the fruit itself contains these compounds, they are particularly concentrated in the leaves, stems, and roots. Therefore, consuming these parts of the plant raw poses a higher risk of toxicity.
Symptoms of Elderberry Poisoning
The symptoms of elderberry poisoning can vary in severity depending on the amount of cyanogenic glycosides ingested and the individual’s sensitivity. Common symptoms include:
- Nausea
- Vomiting
- Diarrhea
- Stomach cramps
- Weakness
- Dizziness
In severe cases, cyanide poisoning can lead to:
- Difficulty breathing
- Seizures
- Loss of consciousness
- Even death (though rare from elderberry consumption)
If you suspect elderberry poisoning, seek immediate medical attention. The sooner treatment is administered, the better the outcome.
Minimizing the Risk: Proper Preparation is Key
The key to safely enjoying the potential benefits of elderberry lies in proper preparation. The good news is that cooking significantly reduces the concentration of cyanogenic glycosides, making the berries safe for consumption.
Heat degrades these compounds, neutralizing their toxic effects. It is therefore crucial to always cook elderberries thoroughly before eating them.
Here are some guidelines for safe elderberry preparation:
- Never eat raw elderberries, leaves, stems, or roots.
- Cook elderberries at a high temperature (above 176°F or 80°C) for at least 30 minutes.
- Remove all stems and leaves before cooking.
- Ensure the berries are fully ripe. Unripe berries may contain higher levels of cyanogenic glycosides.
Elderberry juice and syrup purchased from reputable manufacturers are typically safe, as they have undergone processing to remove or neutralize the toxic compounds. However, always check the product label and follow the manufacturer’s instructions.
Elderflower: A Different Story
While the raw berries, leaves, stems, and roots of the elderberry plant can be toxic, the elderflowers are generally considered safe to consume after proper preparation. Elderflowers are often used to make teas, syrups, and other culinary delights.
However, even with elderflowers, it’s essential to exercise caution. While they contain less cyanogenic glycosides than other parts of the plant, they still contain trace amounts. Some people might be more sensitive than others.
Proper preparation of elderflowers involves:

Elderberry and Amygdalin (Vitamin B17)
Sometimes, elderberry toxicity is confused with concerns surrounding amygdalin, also known as “Vitamin B17” or laetrile. Amygdalin is a cyanogenic glycoside found in the seeds of various fruits, including apricots, peaches, and almonds. While amygdalin is not directly related to elderberry, the fear surrounding it sometimes gets conflated with elderberry concerns because both contain cyanogenic glycosides.
It is important to note that amygdalin has been widely debunked as a cancer treatment and is considered potentially dangerous. The FDA has not approved amygdalin for any medical use, and its use can lead to cyanide poisoning. While both contain cyanogenic glycosides, the context, concentration, and preparation methods differ significantly between amygdalin and elderberry.
