Their scientific heritage plays an important role in the development of Central Asia, and indeed the entire world civilization. Uzbekistan has a rich and ancient history, emerging as a center of science, trade and culture along the Great Silk Road. The scientific heritage created by our ancestors is an important component of world civilization. Today, New Uzbekistan is striving for sustainable development through democratic reforms, economic modernization and consistent social changes. Great scientists from Uzbek lands - Abu Ali ibn Sina and Abu Rayhan Beruni - made an invaluable contribution to the development of the science of medicinal plants. Abu Ali ibn Sina's "Al-Qanun fit-Tibb" ("The Canons of Medicine") describes more than 800 medicinal plants, animals and minerals, while Abu Rayhan Beruni's "Kitab as-Saydana fit-Tibb" ("The Book of Medicine") describes more than 1,000 medicinal plants, animals and minerals. Abu Ali Sino was a polymath, physician, mathematician, astronomer, physicist, chemist, geographer, geologist, and statesman from Transoxiana. He is one of the most famous and influential philosophers and scientists in the world, especially notable for his works in the fields of philosophy and medicine. His main works are two comprehensive scientific and philosophical encyclopedias, "Kitab ash-Shifo" and "Al-Alay Encyclopedia", as well as one of the most famous works in the history of medicine, "Al-Qanun fi at-Tibb". Today, scientific research is being conducted on the basis of this scientific heritage in the Laboratory of Raw Material Plant Introduction and Agroecology of the Tashkent Botanical Garden named after Academician F.N. Rusanov of the Academy of Sciences of Uzbekistan. Through these works, the scientific heritage of our ancestors is widely promoted and serves the development of modern medicine and pharmaceutical industries.
