1. Introduction: What is guanabana called in German?
Guanabana—the name conjures up exotic adventures and tropical mysteries. But what is this fruit that is attracting more and more attention? If you search for “guanabana German”, you will find several names: Stachelannone, Sauersack, or the international names soursop and graviola. All these names refer to the same fascinating plant: Annona muricata.
In this in-depth article, we explore the world of guanabana. We explain where it comes from, what it tastes like and how it has traditionally been used. We also look at scientific research, which points to both promising potential and serious risks. Join us to understand guanabana in all its aspects and make an informed choice about enjoying it.
🌿 About GUYA and our work
At GUYA, we work directly with Kichwa communities in Ecuador’s Napo region. Guanabana grows there in traditional chakra forest gardens that protect Amazonian biodiversity. Our mission is to offer authentic products while being transparent about their properties and safe use.
2. Origin and botany: soursop in detail
Guanabana is native to tropical regions of South America and the Caribbean. Countries such as Colombia, Ecuador and Brazil are among its places of origin. Botanically, it belongs to the custard apple family (Annonaceae) and is, surprisingly, a huge berry. It can grow up to 40 centimetres long and weigh up to 4 kilograms.
The evergreen tree Annona muricata can grow up to 12 metres tall and has a relatively sparse crown. Its leaves resemble those of bay trees. The fruit’s distinctive green skin is covered with soft, harmless spines, which give it the German name “Stachelannone”. Inside is juicy white flesh threaded with black seeds.
3. Taste and preparation: how do you eat guanabana?
One of the most common questions is: “What does guanabana taste like?” Its flavour is a unique experience: a complex blend of sweet and tangy notes, often described as pineapple, strawberry and banana with a hint of citrus. The flesh is soft, creamy and almost custard-like.
To enjoy a fresh guanabana:
- Wash the fruit and cut it in half.
- Scoop out the white flesh.
- Remove the black seeds; they are not edible.
- Enjoy the flesh as it is or use it in another recipe.
Guanabana is used in many ways around the world. In South America, it is used for juices, ice cream and smoothies. In Indonesia, it is made into a kind of pudding, while in the Philippines even unripe fruit is eaten as a vegetable.
4. Traditional use in the Amazon
In the Amazon, guanabana is more than just a fruit. For Indigenous Kichwa communities in Ecuador, it has been part of ethnobotanical knowledge for centuries. Traditionally, the leaves are prepared as an infusion and used to relieve fever, pain and inflammation. Across South America, it is valued for its calming and balancing effects, particularly during stress and restlessness.
5. Two sides of guanabana: scientific findings
Modern science has studied guanabana and uncovered a fascinating paradox. The plant contains bioactive compounds called acetogenins, of which annonacin is the best known.
🔬 The two sides of annonacin
Effect 1 – potential anticancer activity:
In laboratory studies (in vitro), acetogenins have shown cytotoxic effects against various cancer cell lines, including breast, lung and pancreatic cancer [1, 2]. The proposed mechanism: annonacin blocks energy production (ATP) in cell mitochondria. Because cancer cells need a great deal of energy, this can cause them to die. These findings are experimental and cannot be directly applied to people.
Effect 2 – neurotoxicity:
The same mechanism that deprives cancer cells of energy also poses a risk. Nerve cells—especially dopaminergic neurons involved in movement coordination—also require a lot of energy. Studies, including one on the Caribbean island of Guadeloupe, have reported an association between high, long-term guanabana consumption and a higher rate of atypical Parkinson-like disorders [3]. Annonacin was found to be highly toxic to these nerve cells.

6. Finding the right balance: therapeutic use vs. prevention
What does this mean for you? Should you avoid guanabana? The answer depends on dose and frequency. We need to distinguish therapeutic use from enjoying it for prevention.
✗ Daily prevention – not recommended
Daily consumption of guanabana or highly concentrated extracts for general health prevention is not recommended. The neurotoxic risks outweigh potential benefits here, as annonacin may accumulate in the body.
✓ Occasional enjoyment – safe and beneficial
If you are healthy and want to enjoy guanabana for its flavour and antioxidant properties, occasional consumption (e.g. 1–2 times per week) is safe—whether as guanabana tea or fruit. At this frequency, the risk of toxic accumulation is minimal, and you can benefit from the plant’s positive aspects.
7. GUYA guanabana tea: sustainable enjoyment from Ecuador
Our GUYA guanabana tea is made from 100% dried leaves of the plant, sustainably grown by our partner communities in Ecuador. It is the perfect choice for safe, occasional enjoyment.
The tea has a mild, slightly bitter flavour and is ideal for relaxed moments. To prepare it, pour boiling water over 1–2 teaspoons of leaves and leave to steep for 5–10 minutes. This lets you discover the traditional side of guanabana without risk.
8. Conclusion: enjoying the ‘miracle fruit’ mindfully
Guanabana, known in German as Stachelannone, is a fruit with two sides. It offers a distinctive flavour, a rich tradition and interesting compounds that are attracting scientific attention. At the same time, excessive consumption carries serious risks. The key is to enjoy it mindfully and in moderation. As an occasional tea or exotic ingredient in cooking, it can be a welcome addition—but daily consumption as a dietary supplement is not recommended.
9. Frequently asked questions (FAQ)
