Anti-tubercular activity of eleven aromatic and medicinal plants occurring in Colombia. (1/2)

INTRODUCTION: Human tuberculosis is a contagious-infectious disease mainly caused by Mycobacterium tuberculosis. Although regimens exist for treating tuberculosis, they are far from ideal. Development of effective strategies for treatment of human tuberculosis has posed a challenge, considering the increase in infections associated with the human immunodeficiency virus and immunocompromised patients. Essential oils--volatile, aromatic oil extracts from plants--have been used in traditional treatment of many diseases; however careful investigation of these oils has not been undertaken with respect to treatments of tuberculosis. OBJECTIVE: The in vitro antitubercular activity of essential oils from 11 medicinal plants grown in Colombia were assessed for efficacy as new medications (phytomedicines) for treatment of M. tuberculosis H37Rv. MATERIAL AND METHODS: Essential oil extraction and analysis were performed as described Stashenko et al. (2004). Minimal inhibitory concentrations were determined by a colorimetric macrodilution method, following the protocol described by Abate et al. (1998). Isoniazide and rifampin were used as control treatments. Bactericidal and bacteriostatic activity was measured using the method developed by the Clinical and Laboratory Standards Institute consigned in the M26-A protocol. RESULTS: Essential oils from Achyrocline alata and Swinglea glutinosa were the most active with minimal inhibitory concentrations of 62.5 +/- 0.1 and 100 +/- 36 microg ml(-1), respectively. Carvacrol, thymol, p-cymene, 1,8-cineole, limonene, and beta-pinene were the major components, most often identified in the 11 plant extracts of essential oils. Time-kill curve assays demonstrated the bacteriostatic activity of these essential oils. CONCLUSIONS: The essential oils from A. alata and S. glutinosa plants, and the components identified therein, are candidates as potential phytotherapeutic agents for human tuberculosis control.  (+info)

I apologize for any confusion, but "achyrocline" is not a medical term or condition. It is actually the name of a genus of plants in the family Asteraceae, also known as the daisy family. The most common species is Achyrocline satureioides, which is native to South America and has been used in traditional medicine for various purposes.

If you have any questions related to medical terminology or health concerns, I would be happy to try to help answer them for you.

"Gnaphalium" is a term that refers to a genus of flowering plants in the family Asteraceae. Commonly known as cudweeds, these plants are native to temperate regions of the Northern Hemisphere, with some species found in South America and South Africa. The leaves of many Gnaphalium species are covered with small hairs that give them a soft, woolly texture.

However, "Gnaphalium" is not a term commonly used in modern medical terminology. While some Gnaphalium species have been used in traditional medicine, there is limited scientific evidence to support their effectiveness for specific health conditions. Therefore, it is important to consult with a healthcare provider before using any herbal remedies or supplements.
