The Publishing House of "Sadecki Bartnik" has released a series of films devoted to the topic of honey and bee products in the context of their medicinal properties. The fourth part of the series presents the person of Prof. Bogdan Kedzia from the Institute of Natural Fibres and Medicinal Plants in Poznan. He explains explicitly every aspect of royal jelly including its newly discovered property of treating infertility. It has been proved that royal jelly also possesses energizing and cleansing qualities. It alleviates symptoms of many illnesses and it helps healing processes. The research shows that no other substance has nor similar beneficial biological properties neither similar composition. The film is undoubtedly a rich source of information on royal jelly: its chemical composition, healing and preventive properties (especially in treating coronary artery disease, hypertension, neurosis, low immunity and diseases of older age), dosage and even application in cosmetics. What is more, this episode provides a lot of information about the production and the importance of royal jelly in the world of bees. We highly recommend the film as it reveals all the secrets of a beehive with the help of a rich and unique graphic material. You can buy the film in our online shop.
