According to another research done by the National University of Singapore, which was published for the first time in 2005, the stipe of the Golden Needle mushroom has protein in large quantities. These proteins, known as ‘Five’, assist in regulating the immune system. The research found that the Golden Needle mushroom also has flammutoxina, a protein that is cardiotoxic and cytolytic. The tests further showed that the protein could be taken orally without any risk of toxicity
