Plants need to defend themselves from attack by micro-organisms, in particular fungi, and they do this by producing anti-fungal chemicals that are toxic to fungi. Because fungal and human cells are similar at a biochemical level it is often the case that chemical compounds intended for plant defence have an inhibitory effect on human cells ...
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria. [1]
Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. — Otto H. Warburg, [ 22 ] Warburg continued to develop the hypothesis experimentally and gave several prominent lectures outlining the theory and the data.
Many plant species have been studied thoroughly for their value as a source of medicine. [ 6 ] [ 7 ] They have a wide range of benefits such as anti-fever and anti-inflammatory properties, can treat diseases such as malaria and diabetes , and are used as vitamins and antibiotic and antifungal medications.
The post-glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells. [6] Although plants are net consumers of carbon dioxide and producers of oxygen via photosynthesis, plant respiration accounts for about half of the CO 2 generated annually by terrestrial ecosystems.

Chaparral (or Larrea tridentata) – a plant used to make a herbal remedy which is sold as cancer treatment. Cancer Research UK state that: "We don't recommend that you take chaparral to treat or prevent any type of cancer." [67] Chlorella – a type of algae promoted for its health-giving properties, including a claimed ability to treat cancer ...
1966 – Taxol, anti-cancer compound, isolated from the yew plant; 1967 – Camptothecin, anti-cancer compound, isolated from the Camptotheca acuminata, the Chinese Happy Tree, which was used as a cancer treatment in traditional Chinese medicine. [23] It is the source of chemotherapy drugs: topotecan and irinotecan.
Further experiments to prove that the oxygen developed during the photosynthesis of green plants came from water were performed by Hill in 1937 and 1939. He showed that isolated chloroplasts give off oxygen in the presence of unnatural reducing agents like iron oxalate , ferricyanide or benzoquinone after exposure to light.
