5. Buy hibiscus tea – organic, loose or tea bags?
When purchasing hibiscus tea, there are significant differences in quality, origin , and ingredients. Whether loose flowers, tea bags, or organic quality – each option has its advantages and disadvantages. It's especially important to pay attention to the tea's origin, as most products are contaminated with pesticides or harmful substances.
Organic products, and especially organic products from permaculture, contain the most nutrients and vitamins. This difference compared to conventional foods is due to the fact that plants from permaculture, especially from permaculture, grow more vigorously and produce more antibodies. These antibodies, in turn, are often the very active substances that are beneficial to us humans.

5.1. Loose tea bags vs. tea bags – Which is better?
The flowers are available in two main forms: loose flowers or tea bags.

- Tea bags: Quick and easy to prepare, but often finely ground and with fewer antioxidants.
5.2. Why organic permaculture is the better choice
When buying food, you should look for organic quality . Conventionally grown hibiscus plants can be contaminated with pesticides that dissolve in the infusion. That conventional food It has now been proven by many studies that they contain residues of pesticides.
Organic tea is grown more sustainably, contains higher amounts of secondary plant compounds , and preserves the original flavor of the flower. Therefore, when making your purchase, you should always pay attention to the manufacturer's transparent information about its origin. The organic seal alone is no longer sufficient these days. It almost exclusively regulates the fertilization method, but says nothing about the cultivation method. Thus, conventional products with an organic seal can still be responsible for the deforestation of vast areas of rainforest . Only permaculture cultivation prevents this. You can learn more about our " Chakra Seal " in the linked blog post.
