August Phytochemicals! From balsa wood rafts to oleandrin

On this date in 1947, Thor Heyerdahl's balsa wood raft "Kon-Tiki" crashed into a reef in Polynesia having crossed 5000 miles of Pacific Ocean in 3.5 months. The raft's strength came from lignin, but also cellulose - the most abundant organic polymer on Earth. #PhytochemicalFriday

Happy #PhytochemicalFriday! Today: helenalin, a sesquiterpene lactone from Arnica montana (Asteraceae: sunflower family!). Though a toxic (plant defense?) compound, it appears to be able to inhibit human telomerase and is thus being investigated as an antitumor agent.
#PhytochemicalFriday? Oleandrin. Cardiac glycoside of the poisonous plant Nerium oleander and cousin of digoxin, Bond's poison in Casino Royale. As @wayneriekhof correctly points out: < 1% of hits in antiviral screens are effective drugs. Let patience and hard evidence guide us.
Happy #PhytochemicalFriday - you made it! Today: amarogentin - a characteristic component of bartenders' aromatic bitters. Isolated from gentian roots, this glycoside is one of the most bitter compounds known to human kind and is used as a standard in measuring bitterness.

  2. I have suffered from herpes since I was young. It is only the last few years I got to know so I started to look for a cure. I went to several hospitals but to no avail. So I came here online to see if I could find a cure so I came across a page here a man was sharing testimonies about Dr Ohikhobo for his natural herbs cure for herpes so I decided to give it a try it only took two weeks of me taking his herbs and I was completely cured from herpes. contact Dr Ohikhobo today if you want to be cured from herpes or any kind of disease too .
