• Examples of Indigenous Science - YOYO


  • This toy was a product of the creative mind of Pedro Flores. The Americans mass produced it and became one of the most distinct toys in history. This was used by people then to fight intruders and Spaniards.
• Examples of Indigenous Science - Medical Incubator


  • Invented by Dr. Fe del Mundo to regulate the body temperature of newborn babies. In a bid to help families in rural communities without electricity, del Mundo invented a bamboo incubator in 1941.
• Examples of Indigenous Science - Jaundice Relieving Device


  • Dr. Fe del Mundo is credited with studies that lead to the invention of an improved incubator and a jaundice relieving device. She has dedicated her life to the cause of pediatrics in the Philippines.
• Examples of Indigenous Science - Erythromycin


  • Discovered by Dr. Abelardo Aguilar in 1949. It is produced by the bacterium Streptomyces erythreus found in the soil from Iloilo. The antibiotic he discovered didn't receive due credit from Eli Lilly and Company, the pharmaceutical firm he worked for. Eli Lilly and Company branded it Ilosone (after Iloilo)
• Examples of Indigenous Science - Patis or Fish Sauce


  • Ruperta David or Aling Tentay was the woman behind the discovery of this condiment. She discovered in 1940s and now a nationwide business and had been registered as Tentay Food & Sauces in 1949.
• Examples of Indigenous Science - Banana Catsup


  • When tomato imports were halted, Maria Orosa Ylagan created banana ketchup using saba bananas, vinegar, sugar, and spices, as an alternative to American-style ketchup. She also discovered calamansi nip, and powdered preparation of soya beans called soya-lac.
• Examples of Indigenous Science - Anticancer Cream


  • Rolando de la Cruz developed an anticancer cream from cashew nuts and other local herbs to treat BSC, a skin cancer. He called this cream DeBCC anticancer cream. He won in the International Inventor's Forum in Nov 2005.
• Examples of Indigenous Science - Mole Remover


  • Another invention made by Rolando de La Cruz was the Mole Remover. It is a cream formulated to remove warts and moles on the skin.
• Examples of Indigenous Science - 16-bit Microchip


  • Diosdado Banatao developed the first single chip graphical user interface accelerator. This chip allows the computer users to make graphical presentation using graphics for commands. Data processing is made much quicker.

• Examples of Indigenous Science - Coral Reef Rehabilitation


  • Dr. Angel C. Alcala may be best known for his research related to the rehabilitation of coral reefs. In 1977, he created the first artificial reef, and this reef became a model for many other fisheries development programs around the world.
• Other Inventors from 2005-present in the Philippines

  • Carvey Ehren Maigue - He successfully converted damaged crops into a solar window. His invention, AuREUS, was inspired by how the Aurora Borealis is formed. Aureus makes use of a substrate (a live substance that produces a chemical reaction) that converts UV light into visible light.
  • The team of biomedical engineers from De La Salle University (DLSU), led by Dr Nilo Bugtai - They created, AGAPAY, a robotic exoskeleton prototype with a biofeedback mechanism for rehabilitation of post-stroke and injured patients by assisting motor movements in the shoulder, arm, and hand.
  • A research team consisting of pulmonologists and biomedical engineers, led by Dr Abundio Balgos of UP Manila - They developed GINHAWA, a low-cost, compact, and effective ventilator that both adults and children can use safely. This project has the potential to help many patients who are severely ill due to COVID-19.
