Mitochondrial toxicity is a condition in which the mitochondria of a body's cells become damaged or decline significantly in number; it occurs as a side effect of certain antiretroviral drugs used to treat human immunodeficiency virus, or HIV. [1]
Causes[edit]
While the exact causes of mitochondrial toxicity are unknown, research has shown that a certain group of anti-viral drugs used to treat HIV, specifically nucleoside analog reverse transcriptase inhibitors (NRTIs), interfere with an enzyme needed in the production of mitochondria.[2]
Symptoms[edit]
The disruption of cell function that accompanies the condition can cause both mild and severe problems in people with mitochondrial toxicity. The most commonly observed symptom is muscle weakness, or myopathy. Others include peripheral neuropathy (numbness in the fingers and toes) and pancreatitis (inflammation of the pancreas), with the most severe being lactic acidosis, in which a build-up of lactic acid in the tissues of the body leads to loss of energy, organ failure, and eventually death.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
