Chamomile (Matricaria chamomilla, synonym Matricaria recutita) is an annual, aromatic plant from the Asteraceae family. Originally native to large parts of Europe, it is now widely cultivated, including in Hungary and several Eastern European countries.
Chamomile has a long cultural and historical background. In ancient Egypt, the plant was symbolically worshipped and associated with the sun god Ra. Throughout the centuries, chamomile has been frequently described in botanical and historical sources, contributing to its fame and spread.

Kelp, a member of the brown algae (Laminariales) family, thrives in the cold waters of the major oceans. This large species of seaweed is an excellent source of iodine, an essential element for healthy thyroid function in humans.
In Asia, especially Japan, seaweed has been an integral part of the daily diet for centuries. A well-known kelp species is kombu (Laminaria japonica), which is often cooked with rice for sushi. In addition to being one of the largest plants in the world, kelp is known for growing extremely quickly, sometimes up to three meters per day.

Cat's whiskers (Orthosiphon aristatus), also known as Kumis Kutjing, is a plant traditionally used in various Asian herbal traditions. The species belongs to the Lamiaceae family and is native to tropical and subtropical regions, particularly Southeast Asia, including Malaysia and Java.
The plant prefers moist habitats, such as wetlands, riverbanks, and swampy areas. Cat's whiskers are particularly recognizable by their white to pale lilac flowers with conspicuously long, thread-like stamens that can grow up to approximately three centimeters long. These characteristics have led to the Dutch name "kattensnor" (cat's whiskers).

Moringa oleifera, often called the "tree of life," is a plant native to parts of Africa and Asia. The leaves of the moringa tree contain various nutrients, such as vitamins, minerals, proteins, and antioxidants.
In many Asian and African cultures, moringa has been used for centuries as part of the daily diet. The leaves can be incorporated into meals or used as a supplement for their nutritional value.

Oregano (Origanum vulgare), also known as wild marjoram, is an aromatic herb that has been used for thousands of years in various cuisines and cultures. The herb belongs to the Lamiaceae family, which also includes rosemary, thyme, and mint.
Oregano naturally contains several plant compounds, including carvacrol, which is responsible for its characteristic spicy and slightly bitter flavor. This compound contributes to oregano's distinct aroma.
The most aromatic oregano grows naturally in Mediterranean mountain regions on calcareous soils. Wild oregano blooms in spring, after which it is traditionally harvested. Thanks to its flavor and composition, oregano is widely used in culinary applications and herbal teas.
