Punarnava benefits for liver
Ethnopharmacological (based on common usage amongst people) studies suggest that punarnava is considered the best remedy for most liver problems in traditional and folk medicine systems. Based on these claims, various in vivo (animal-based) studies have been done to confirm the hepatoprotective potential of punarnava.
A Vivo-based study suggests that the administration of the root extracts of punarnava leads to a significant decrease in serum alanine aminotransferase (ALT) levels in the body. ALT is an enzyme that is commonly released by the liver for various body functions but an excess of ALT indicates improper liver functioning.
A further study suggests that the best time to harvest punarnava is in May when its roots reach a diameter of 1-3 cm. It was noted that the aqueous extracts of such roots have excellent hepatoprotective benefits. It was further claimed that the aqueous form of this herb is much more potent than the powdered form in maintaining good liver health.
However, in a recent case study, an ayurvedic formulation known as Punarnava matter has been reported to show some hepatotoxicity. It is strongly recommended that you refer to an Ayurveda doctor to know the right dosage of any herb for you.
Punarnava benefits kidneys
Punarnava leaves, roots, and the whole plant has been in use by the tribal and traditional medicine systems for the treatment of various kidney problems. Laboratory-based studies suggest that aqueous extracts of punarnava have a marked inhibitory effect on the formation of kidney stones. Several animal-based studies suggest the diuretic and nephroprotective benefits of punarnava. A further in vivo study hints that punarnavine, a water-soluble chemical compound present in punarnava roots is primarily responsible for the diuretic properties of this herb.
According to a case study mentioned in the International Journal of Advanced Ayurveda, Yogi, Yunani, Siddha, and Homeopathy, an ayurvedic formulation made of punarnava was given to a patient suffering from chronic kidney failure (CHF, which refers to a gradual decline in kidney function) for six months. At the end of six months, significant improvement in kidney function was reported. Additionally, it was claimed that the person did not need dialysis anymore.
Another clinical study suggested that Punarnavadi, an ayurvedic formulation may be beneficial in reducing the risk of chronic kidney failure. However, more studies are needed to confirm the exact mechanism and dosage of punarnava for the treatment of various kidney disorders.
Punarnava for anemia
According to ayurveda, puAyurvedais an excellent agent for correcting iron deficiencies in the body. Punarnava Mandur, an ayurvedic formulation is being used as an anti-anemic agent by the National Rural Health Mission in India.
Punarnava mandir is traditionally given with buttermilk. This is because iron is known to be absorbed better at lower pH levels. In a recent clinical study, 50 patients with geriatric anemia (associated with old age) were given two tablets of Punarnava mandur twice a day with buttermilk for 90 days. A marked reduction in anemia symptoms was reported in all the patients.
It is always recommended that you talk to your ayurvedic doctor before taking any ayurvedic formulation.
Punarnava for asthma
According to an article in the Journal of Pharmacognosy and Phytochemistry, punarnava stimulated the removal of mucus from the respiratory tract. Pre-clinical studies suggest that punarnava leaf extracts exhibit significant tracheoralaxant effects. So, it is speculated that punarnava may have some future use in anti-asthma treatments. No human studies are available so far to confirm the possible benefits of punarnava for asthma patients.
Punarnava for diabetes
In vivo studies indicate that leaf extract of punarnava is an efficient hypoglycemic (reduces blood sugar levels). It was further suggested that regular consumption of punarnava leaf extracts increases the level of insulin in the body thus leading to lower blood sugar levels. Another study suggests that punarnava reduces blood sugar levels by renewing beta cells in the pancreas (cells responsible for insulin secretion). In the absence of clinical trials, it is best to check in with your ayurvedic doctor to know more about the anti-diabetic effects of punarnava.
Punarnava antimicrobial benefits
Numerous lab studies suggest the antimicrobial potential of the punarnava plant.
In a punarnava plant study, various extracts of punarnava leaves (aqueous, ethanol, methanol, chloroform, etc.) were found to be effective against a wide range of bacteria including Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, etc.
Another study suggests that the water and ethanolic extracts of the punarnava plant exhibit strong antimicrobial action against bacterial pathogens like Escherichia coli, Bacillus subtilis, Salmonella typhimurium, Neisseria gonorrhoeae, Corynebacterium diphtheriae, Shigella dysentery, Clostridium tetani, etc. However, there is no confirmatory evidence of the antimicrobial activities of punarnava in humans.
Punarnava for immunity
According to ayurvedic doctors, punarnava is a nourishing herb. This means that consuming punarnava leads to the overall development of our body functions. Immunity is one of the major body functions responsible for keeping off infections and diseases from our bodies. Punarnava as a health-building herb can act as an immunomodulant (improves immunity) thus keeping us from falling sick. In vivo studies suggest that punarnava extracts mediate a stimulatory effect on lymphocytes (white blood cells) and other immune system cells was further claimed that the adaptogenic (stress reducing) effects of punarnava are comparable to that of ashwagandha.
According to a review article published in the Journal of Microbiology, Immunology, and Infection, the alkaloid content of punarnava is primarily responsible for its immuno-stimulatory effects. However, there have been studies that hint at selective immuno-suppressive (suppresses the immune system) activity by ethanolic root extracts of punarnava.
Hence, it is best to refer to an ayurvedic doctor to know more about the mechanism of action of punarnava on your immune system.
Punarnava for menstrual problems
Traditionally, punarnava is used for the treatment of female menstrual disorders like irregular menstruation (amenorrhea) and menstrual pain (dysmenorrhea). Studies suggest that punarnava may have some antifibrinolytic potential (stops clot formation). Animal-based studies suggest that the consumption of punarnava may be useful in regularising menstrual flow and decreasing common menstrual problems like cramps, inflammation, swelling, etc in the uterus. However, more studies are still needed to find the exact mechanism and dosage of punarnava in the treatment of the menstrual condition.
Punarnava antioxidant properties
In vitro (lab-based) and in vivo studies suggest that punarnava is an excellent antioxidant. In a laboratory-based study published in the International Journal of Pharmacognosy and Phytochemical Research, the phenolic and flavonoid content of punarnava is responsible for most of its antioxidant properties.
Another in vitro study claims that the antioxidant effects of punarnava can be attributed in part to the high Vitamin C and polyphenol content of punarnava.
Punarnava for inflammation
Punarnava has been in use as an anti-inflammatory herb by several folk traditions and cultures. Many ayurvedic anti-inflammatory formulations have punarnava as one of their main ingredients. Pre-clinical studies hint that punarnava leaves may have some anti-inflammatory and analgesic (pain-reducing) properties. Another lab study adds that the anti-inflammatory potential of punarnava is at its peak during the rainy season. However, clinical trials are still pending to confirm a similar action in human-based inflammatory conditions.
Punarnava for stress
Punarnava is known as a Rasayana (rejuvenator) in Ayurveda. According to ayurvedic doctors, every Rasayana herb has a stress-relieving ability. Studies suggest that punarnava extracts and the ayurvedic formulation Punarnava mandir are efficient anti-stress agents.
According to a review article published in the International Journal of Pharmacy and Pharmaceutical Sciences, the major adaptogenic agent present in the punarnava plant is boeravinone.
Punarnava for eyes
A human study-based report suggests that punarnava leaf and root extracts have been used as a folk remedy for the treatment of various eye disorders. An eye drop is made with punarnava leaf juice and honey to reduce inflammation in common eye problems like conjunctivitis. The juice of punarnava root is also used as a remedy for night blindness in folk medicine.
In an in vivo study, punarnava gel and eye drops were found to be useful in alleviating cataract and conjunctivitis symptoms. It was further reported that administration of punarnava gel or eye drops did not have any significant adverse effect.
However, due to the lack of clinical trials, you should talk to your Ayurveda doctor before using punarnava for any kind of eye condition.
Punarnava for weight loss
While there has been no evident research on the efficiency of punarnava as a weight loss agent, it remains one of the top ayurvedic herbs used in weight loss formulations. One theory suggests that punarnava, as a diuretic, may help reduce the excess fluid weight from the body. Additionally, punarnava is also known to be a mild laxative.
It is further suggested that punarnava inhibits the retention of fluids in the body thus helping indirectly in losing weight. However, most of this weight loss function seems to come from the fluid balance in the body and not much can be confirmed about the action of punarnava in reducing fat in tissue. But, it might be beneficial as a supplement with regular exercise. You should talk to your doctor before using punarnava in any anti-obesity therapy.
Punarnava benefits for skin
Punarnava is well known for its skin healing benefits in Ayurveda and folk medicine.
Ethnopharmacological studies suggest that punarnava root and leaves have been used to treat various skin disorders by the tribals of central India.
Punarnava has been claimed to be an excellent antioxidant, antibiotic and anti-inflammatory herb. Additionally, punarnava is also known as an adaptogen and Rasayana. Together, these three properties make punarnava an all-healing and rejuvenating herb for the skin. Using punarnava may not only help reduce common skin ailments like itching, and rashes, but it will also fight off any infectious bacteria present on the skin.

Various in vitro and in vivo studies suggest that punarnava has a potent antiproliferative (stops the spread of) action against cancer cells.
Lab-based studies suggest that punarnava extracts inhibit the growth of cancer lymphocytes. Another study claims that punarnava has two chemical compounds named boeravinone 1 and 2. which stop the chemotherapy resistance in some breast cancer cells. In vivo studies suggest the protective effect of punarnava against radiation-induced damage. However, a lot more research is still needed to understand the anticancer efficiency of punarnava.
Punarnava is mostly used in the form of ayurvedic formulations like Punarnava mandur and Punarnava guggulu. It is also prescribed by some ayurvedic doctors in the form of Punarnava powder, tablets, and capsules.
Punarnava paste is used in some traditional remedies for skin problems.
Punarnava tea, decoctions (kadhai), and eye washes have also been in use. Apart from its medicinal benefits, punarnava leaves are also used as food in some parts of West Bengal and Assam.
