[What is Rhodiola Rosea]

Rhodiola Rosea (also known as Arctic root or golden root) is a member of the family Crassulaceae, a family of plants native to the arctic regions of Eastern Siberia. Rhodiola rosea is widely distributed  in Arctic and mountainous regions throughout Europe and Asia. It grows at altitudes of 11,000 to 18,000 feet above sea level.

There are numerous animal and test tube studies showing that rhodiola has both a stimulating and a sedating effect on the central nervous system; enhance physical endurance; improves thyroid, thymus, and adrenal function; protects the nervous system, heart and liver; and has antioxidant and anticancer properties.

[Function]

1 Enhancing immunity and delaying aging;

2 Resisting radiation and tumor;

3 Regulating nervous system and metabolism, effectively limiting melancholy feeling and mood, and promoting mental status;

4 Protecting cardiovascular, dilating coronary artery,preventing coronary arteriosclerosis and arrhythmia.

Oncology questions

Have you ever wondered what determines your height, hair and skin color and even the size of your nose?

It’s DNA, the genetic material of cell. But do you know how it has been proved?

Here are the experiments that proved it.

Griffith’s Experiment:

Griffith took two strains of pneumococcus bacteria.

1. S (III) – which have smooth polysaccharide capsule, giving smooth colonies (S) and is virulent causing pneumonia.

AND

2. R (II) – which have no capsule, giving Rough colonies (R) and is avirulent unable to cause pneumonia.

When the virulent S (III) bacteria injected in mice, it killed them causing pneumonia.

But when the Avirulent R (II) injected in mice, the mice lives

If you inject the heat killed virulent S (III) bacteria, the mice still live. Implying that live S (III) bacteria are needed for causing pneumonia

But interestingly, when mice were injected with the mixture of heat killed virulent S (III) bacteria and avirulent R (II) bacteria, mice died.

Analysis of dead mice reveals live S (III) virulent bacteria suggesting something form the heat killed S (III) had transformed to the live avirulent R (II) bacteria, responsible for the transformation of the live avirulent bacteria to virulent S (III) bacteria, causing death of mice. This is called as Bacterial Transformation.

To prove DNA is genetic material, team of Avery et al and Hershey and chase performed another experiments. See other video for it.
