What is guarana and why is it named so?
Guarana, also known as cierniopląt or osmęta, is a popular name for the plant Paulinia guarana. The name originates from the sour and bitter beverage prepared by the Guarani tribe using the seeds of this plant. The plant is primarily found in Brazil, specifically in the Amazon and Paraná river basins.
Effect of guarana on the body
Guarana contains natural stimulating substances in its structure, including caffeine, catechins, and procyanidins. While the effects of these compounds are well-known, further studies are necessary to determine how they affect the body. Guarana acts as a dietary supplement, aiding in the fight against physical and mental fatigue, and also improving concentration and memory. It may also have anticancer and psychostimulant properties, but these assumptions require further investigation. Paulinia cupana is, however, not a fat-burning stimulant.
Applications of Guarana
Guarana and products containing guarana may be employed in situations such as: - physical and mental fatigue; - compromised immunity; - difficulties with concentration and memory; - headaches and migraines; - disorders related to blood circulation; - periods of recovery following illnesses and surgeries; - depressive states, stress, and nervous disorders.
Administering the proper dose
The recommended amount of guarana should range from 50 to 75 mg daily, preferably before midday. There is also the option of taking two doses of the supplement at 50 mg each, one in the morning (after waking up) and the other in the afternoon. The total amount of the substance should be 100 mg per day. Despite potential recommendations, further detailed studies are necessary to determine the appropriate quantity of medication for the patient. It is not recommended to take guarana in the evening, due to its stimulating and invigorating properties.
Contraindications regarding the use of guarana
Guarana and products containing this ingredient are not recommended for pregnant or breast-feeding women. Individuals suffering from diabetes, hypertension, and heart arrhythmias should exercise caution when taking supplements. Exceeding the permissible amount of guarana may lead to the occurrence of undesirable side effects, such as insomnia, excessive increase in blood pressure, heart palpitations, restlessness, and constipation.
