Boerhaavia Diffusa (Punarnava): A Cheap Yet Powerful Superfood

punarnava health benefits

I like to forage for wild edibles and medicinal plants, but admittedly can’t identify too many.  Boerhaavia diffusa is one plant which I repeatedly saw around the United States.  It wasn’t until I took a trip to India that I finally learned what the plant is.

While there are many amazing plants with medicinal properties, punarnava is one of the best yet underutilized.  Not only does punarnava have lots of benefits, but it is one of the cheapest superfoods and easy to produce.  Here’s what you need to know about the plant and why to use it.

 

What is Punarnava?

punarnava plant growing wild

Punarnava is a plant which is commonly used in Ayurveda medicine as well as many other ancient and folk medicines.  It grows in many tropical and subtropical areas around the world including India, Nigeria, and the United States.

The plant grows close to the ground and spreads out.  Punarnava somewhat resembles purslane (a common edible).  The main difference is that Punarnava has tiny sticky fruits. The fruits stick to animals as they pass by to spread the seeds.   It’s a very hardy plant and you’ll sometimes see it growing out of sidewalk cracks.

 

Other Names for Punarnava

Punarnava is the Sanskrit name for the plant.  It means “rejuvenates the body” in Ayurveda medicine.   In English, punarnava is usually called by its Latin name, Boerhaavia diffusa.

It is also sometimes called red spiderling or tar vine in English.  Sometimes it’s also called spreading hogweed, even though hogweed is a different plant (common hogweed is delicious and has seeds which taste like cardamom).  I’ve also heard punarnava called pigweed before, but that is just a generic term for any plant that which could be used for pig fodder.

Here is a list of names for punarnava, including some of the many local Indian names.  Because punarnava grows in so many countries, there are dozens of other local names too.

  • Boerhaavia diffusa(Latin)
  • Sothaghni (Sanskrit)
  • Varshabhu (Sanskrit)
  • Dholia-saturdo (Gujarati)
  • Snathikari (Hindi)
  • Kommegida (Kannada)
  • Tambadivasu (Marathi)
  • Punurnava (Bengali)
  • Mukaratee-Kirei (Tamil)
  • Punernava (Telugu)
  • Horse purslane (English)
  • Pega-pinto (Brazilian)
  • Huang xi xin (Chinese)

 

Where to Buy Punarnava

Punarnava grows easily in many parts of the world.  Unfortunately though, not all punarnava has the same nutritional and health value.  When grown in poor conditions, the resulting punarnava plant can be very poor quality.

Ideally, you would forage or grow your own punarnava plants.  If that is not possible, then try to choose an organic punarnava product as it’s more likely that quality soil and good farming practices were used. (1)

Below are some of the best punarnava powders and supplements you can buy online.

Even compared to other anti-microbial plants, punarnava has strong antibacterial, anti-fungal and anti-viral benefits.  Studies showed that the plant reduced levels of E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, candida, and viruses. All parts of the plant have anti-microbial benefits but the root has the strongest benefits. (3, 4)

How to Use Punarnava

If you can find or grow punarnava, then you can simply eat the plant leaves raw.  They are a good source of nutrition and have a very fresh, mild taste compared to other greens.  In India, it’s common for people to cook the leaves but this may destroy many of the natural compounds in them.

For health benefits, it’s better to consume punarnava root.  This is where the most helpful compounds are concentrated.  You can dig them up yourself, dehydrate them, and grind them into a powder.  Or simply buy punarnava powder online.

Punarnava powder does have an earthy, slightly bitter taste.  I find it goes best in smoothies with strong-flavors, such as cherries or blackberries.

 

Punarnava Powder Dosage

The standard recommended dosage of punarnava root powder is usually 3 grams, taken one or two times daily.  Consult with your healthcare provider.

 

Cautions

It’s worth noting that punarnava is a slight laxative.  You might want to start by taking just a small dosage of the powder.  See how your body reacts and then increase to the recommended dosage.
