Sexual Health
Also known as “potency wood”, Muira Puama has long been used by the Amazonian people to manage a variety of age related conditions. It is marketed in Brazil as a “body stimulant, energetic tonic and aphrodisiac”. It can be especially useful in supporting healthy erectile response and restoring libido in men suffering the effects of fatigue or age related complaints.
Muira Puama contains “sterols”, the building blocks of sex hormones such as testosterone. One study found that this herb relaxes the corpus cavernosa – a sponge like area that holds blood during an erection. This relaxation allows more blood to flow to the penis, producing a stronger and firmer erectile response. Dr Jacques Maynberg conducted two studies at the Institute of Sexology in Paris, where he gave men stricken with low libido and diminished erectile capacity Muira Puama for two weeks. In both studies between 60% – 70% of the men reported a notable increase in libido and an improvement in their ability to maintain an erection.
A study was done with 202 women to investigate the potential of Muira Puama as a libido boosting herb for women with low sex drives. It was found that after one month of supplementation with this herb that 65% reported improvements in sexual desire and satisfaction. Some of the women also experienced more sexual fantasies and increased orgasm intensity.
Central Nervous System
The indigenous peoples of the Amazon have consumed Muira Puama for centuries as a remedy for a sluggish central nervous system. When this plant was studied by Siqueira et al for its effect on the central nervous system, it was found that, “Muira Puama roots possess various central nervous system activities, including mild anxiogenic effects” – meaning that they help to stimulate the CNS which can lead to increased mental performance and physical stamina.
Studies have found that Muira Puama may also help in improving memory among older individuals. In a study conducted by Brazilian researchers in 2004, aging rats when treated with this herb performed well in memory tests, along with adult mice. This memory enhancing effect is thought to be due to its ability to inhibit acetylcholinesterase. Acetylcholinesterase is an enzyme which breaks down the neurotransmitter acetylcholine, which is necessary for cognition and memory. By protecting acetylcholienesterase, this herb may have therapeutic properties for cognition-impaired and memory affected individuals.


Beginning around 9th century BCE, the Greeks used Marshmallows to heal wounds and soothe sore throats. A balm made from the plant’s sap was often applied to toothaches and bee stings. The plant’s medicinal uses grew more varied in the centuries that followed: Arab physicians made a poultice from ground-up Marshmallow leaves and used it as an anti-inflammatory. The Romans found that marshmallows worked well as a laxative and by the Middle Ages, Marshmallows served as a treatment for everything from upset stomachs to chest colds and insomnia.

The ancient Egyptians used Mashmallow root for making candied delicacies for their gods, nobility and Pharaohs over 2000 years ago. They used the soft, spongy pith of the plant, which was boiled in honey or sugar syrup, to create a chewy candy-like substance – the pre-cursor to our modern day Marshmallows. 

In 19th-century France, candy makers whipped the sap of the Marshmallow plant into a fluffy confection which more closely resembled the modern Marshmallow. Unfortunately, the process of extracting the sap was a laborious task and over time confectioners substituted gelatin for the plant extract.
