Guinea Hen Weed (Anamu): 5 Exciting Benefits of this Amazonian Plant

guinea hen weed amanu health benefits

While living in Peru, I badly sprained my ankle while hiking in the jungle.  A local friend gave me mucura – also known as guinea hen weed or anamu – to help with the inflammation and pain.  While I can’t say with 100% certainty that the plant helped with the pain and swelling, the science backs it up.

While guinea hen weed still isn’t very well known in western cultures, it is starting to get a lot of attention for its anti-inflammatory and anti-cancer benefits. Here’s what you need to know about the medicinal plant and how to use it.


What Is Guinea Hen Weed?

Guinea hen weed is an herb native to the Amazonian rainforest, though it now can be found throughout Central and South America and even parts of the Southern USA.  It grows up to 3 feet tall, has deep roots, small whitish-green flowers, and emits a garlic-like smell.

The leaves and roots of the plant have long been part of natural medicine in the region.  It is mostly used for treating colds, flus, pain, infections, and as an insect repellent.  More recently, the plant has gotten attention as a treatment for cancer.

Other Names for Guinea Hen Weed:

Because guinea hen weed is used by so many cultures throughout the Americas, it has many different names.  Here are just some of the most common ones.

  • Petiveria alliacea (Latin)
  • Amasu
  • Anamu
  • Apacina
  • Mucura
  • Tipi
  • Garlic weed
  • Gully root
  • Apazote de zorro
  • Kojo root


Compounds in Guinea Hen Weed/Anamu

Researchers have isolated many compounds from guinea hen weed.  These include many types of:

  • Flavonoids (astilbin, myricitrin, engeletin, pinitol)
  • Triterpenes
  • Fatty acids
  • Allantoin
  • Coumarin
  • Sulfur-containing amino acids (in the roots)

Individually, these compounds are known to have numerous health benefits.  However, the beauty of natural medicines is that the compounds work together. Whereas traditional drugs tend to work in just one way (such as killing bacteria), the compounds in guinea hen weed can tackle ailments on multiple fronts (such as killing bacteria while boosting immunity and reducing inflammation).

Proven Benefits of Guinea Hen Weed/Anamu

Even though guinea hen weed has been used medicinally for centuries, the plant didn’t get much scientific attention until the early 2000s.  That’s when researchers started seriously investigating its cancer-fighting abilities.  Now, there are thousands of studies showing numerous benefits of guinea hen weed.  Here are just the main ones.


1. Fighting Infections

Like many other Amazonian plants, guinea hen weed has evolved to contain chemicals which help it fight infection.  These same chemicals can help humans fight infections.  In particular, the 18+ sulfur compounds in guinea hen weed have been shown to be very effective in killing bacteria and fungus – including candida and E. coli.  There is also evidence that it helps fight against viral infections too.

In general, the roots of guinea hen weed are considered better than the leaves for fighting infection.  However, the leaves also contain anti-microbial compounds as well as compounds which can boost immunity. (1, 2, 3, 4, 5)


2. Anti-Cancer

While the mechanism is quite complex, compounds from guinea hen weed have repeatedly been shown to kill tumor cells, slow tumor cell growth, and help regulate healthy cell activity. This has been tested against various types of cancers – including breast, colon, and lung cancer.  (6, 7, 8, 9, 10)


3. Inflammation

Numerous animal and cell studies have found that extracts from anamu plant reduce inflammation.  This is likely because of the many antioxidants in the plant and compounds like pinitol, myricitrin, and coumarin – all of which are known to reduce inflammation markers.

Because of these properties, anamu could help treat inflammatory conditions including:

  • Arthritis
  • Rheumatism
  • IBS and IBD
  • Psoriasis
  • Asthma

Traditionally, anamu root and leaves are ground into a paste and applied externally to treat inflammation pain.  However, for systematic inflammation, it can also be taken internally to fight inflammation from the inside out. (11, 12, 13, 14, 15)


4. Skincare

In traditional medicine, anamu is often applied topically to treat rashes and skin infections.  Because it is a natural antimicrobial and anti-inflammatory, anamu can also have many other benefits for skin health, such as reducing redness from acne or treating inflammatory skin conditions like psoriasis.  The plant also contains allantoin, which is well known for helping to reduce scars and speed up wound healing.  Allantoin also helps shed dead skin cells so the skin also becomes smoother. (16, 17)


5. Mental Health and Neuromodulation

There is some research that shows guinea hen weed can have mental health benefits including treating depression and anxiety.  Some studies also show that it can help improve long-term memory. These benefits are mostly linked to the flavonoids, terpenoids and coumarins in anamu, which can help reduce oxidative stress and regulate neurological activity. (18, 19, 20)


How to Use Guinea Hen Weed/Anamu

Both the root and leaves of guinea hen weed can be used medicinally.  You can take them internally as a dried powder, tincture, or infused into a tea.  There is no standard dosage but usually around 1-4 grams of dried herb per day is recommended. It’s also possible to apply guinea hen weed externally.  This is usually done as a poultice or extract mixed into a cream.


Pour 1 cup of boiling water over 1 tsp of anamu powder and let it steep for 10 minutes.  Strain and drink.   Note that anamu tea (especially the root) is pretty bad tasting, which is why you only really want to use a small amount of water to make the infusion as there will be less for you to drink.  It tastes better when consumed cold, so add some ice cubes or let it sit in the fridge before drinking. For medicinal benefits, drink twice per day.


Take 450mg to 3 grams of powdered anamu twice per day.


Take 1-3ml of tincture twice per day.


If you have access to fresh amanu plant, you can beat it into a paste.  Put it between pieces of gauze and apply to the problematic area (such as joints or the temples for treating headache).


Pregnant women and women who are trying to get pregnant should not take amanu.  It can cause uterine contractions and possibly result in miscarriage.  Because the plant contains coumarin, a natural blood thinner, it might not be safe for people who are taking Warfarin or have blood disorders. Always talk to your doctor before taking any medicinal herbs.
