Gen info
- Phyllanthus is the largest genus in the flowering plant family Phyllanthaceae. Estimates on the number of species int he genus vary widely, from 750 to 1200 Diversity of growth forms include annual and perennial herbs, shrubs, climbers, floating aquatics, and pachycaulous 4succulents. It has one of the widest range of pollen types of any seed plant genus. (64)
- Phyllanthus species express a specific type of growth called "phyllanthoid branching" in which vertical stems bear
deciduous, floriferous (flower-bearing), plagiotropic (horizontal or oblique) stems. (64)
- The genus was first described by Carl Linnaeus in 1759.

- Chanca piedra

Antiviral / Anti-Hepatitis B: (1) Studies of extracts have shown marked anti-hepatitis B surface antigen activity possibly through inhibition of viral genetic material. (2) A study reports P niruri has profound effects in vitro on HBsAg, on woodchuck hepatitis virus surface antigen (WHsAg) and on the DNA of both viruses and in vivo on the replication of WHV (woodchuck hepatitis virus) and in some controlled studies, it appeared to eliminate WHV from carriers.
Hypolipidemic: Studies have demonstrated lipid-lowering effects in triton and cholesterol fed hyperlipidemic rats
Anti-diabetic: (1) Studies have shown potential anti-diabetic action of PN. (2) Study of aqueous extract of the plant yielded alkaloids, flavonoids and saponins. Administration of aqueous extracts in mice showed a significant decrease in blood glucose with a significant effect in controlling the loss of body weight. Results showed a hypoglycemic effect in diabetic rats with no evidence of hepatotoxicity.
Anti-malarial: Extract studies of Phyllanthus niruri showed inhibitory activity of Plasmodium falcifarum.
Calculi dissolution: Although test did not show prevention of further growth, PN modified the shape and texture of the stone into a more fragile form which may help in elimination and dissolution.
Platelet Aggregation Inhibition: Methyl brevifolincarboxylate, isolated from PN, was found to have inhibitory effects on platelet aggregation. (5)
Hepatoprotective / Nimesulide Induced Toxicity: Study showed PN to possess hepatoprotective activity against nimesulide-induced liver toxicity, probably through an antioxidant defense mechanism. Another study demonstrated a protein fraction of PN to be protective against acetaminophen hepatotoxicity by increasing antioxidative defense.(6) Study evaluated an aqueous extract of P. niruri on hepatocurative effects from nimesuline (NIM) induced oxidative stress in vivo. NIM administration caused significant depletion of SOD, CAT, and GSH along with increased lipid peroxidation. Treatment with PN rapidly restored most of the NIM-induced oxidative changes, along with supporting histological studies. PN also showed scavenging of free radicals. (46)
Calcium Oxalate Crystal Growth and Aggregation Inhibition: Study showed an inhibitory effect of P niruri extract on CaOx crystal growth and aggregation in human urine, suggesting an interference with the early stages of stone formation and presents an alternative form of treatment and / or prevention of urolithiasis. (11)
Antihyperuricemic Effect: Study showed the methanol extract of P niruri and its lignans were able to reverse the plasma uric acid of hyperuricemic animals. The effect could be through its uricosuric action and partly through xanthine oxidase inhibition. The antihyperuricemic effect of the lignans was attributed to their uricosuric action. A methanol extract of leaves showed dose-dependent oral antihyperuricemic activity in potassium oxonate- and uric acid-induced hyperuricemic rats. (12)
Acute Toxicity Study / Leaves / Aerial Parts: Study of aqueous leaf extract was done in female Sprague-Dawley rats to illicit evidence of toxicity. No toxicity was observed at various levels of testing. The LD50 of the aqueous extract is >5000 mg/KBW. (15)

Anti-Cataract Potential / Galactose Induced Cataractogenesis: Study evaluated the anti-cataract effect of phyllanthus niruri both in vivo and in vitro galactose induced cataract. PN significantly delayed the onset and progression of cataract in vivo. Lenses treated with PN 880 µg/mL concentration showed higher levels of glutathione (GSH) and decreased levels of polyols in vitro. (
Antimetastatic and Apoptotic Effects: Study evaluated the antimetastatic potential of Phyllanthus niruri, P. urinaria, P. watsonii, and P. amarus on lung and breast cancer carcinoma cells. The plant extracts were shown to inhibit MCF-7 (breast carcinoma) and A549 (lung carcinoma) cells growth with IC50 values ranging from 50-180 µg/ml and 65-470 µg/ml for methanolic and aqueous extracts, respectively. Phyllanthus extracts were showed to effectively reduce invasion, migration, and adhesion of both MCF-7 and A549 cells in a dose dependent manner. Phyllanthus showed to be capable of inducing apoptosis in conjunction with its antimetastatic action. The antimetastatic effects is mostly associated to the presence of polyphenol compounds in its extracts. (

Hypoglycemic Effect: Treatment with P. niruri showed remarkable and significant decrease in blood glucose (p<0.05) compared with control NIDDM patients. Use of capsulated dry powder (250 mg/tab) of P. niruri for 2 months showed no side effects. (
39) Study showed the ethanolic extract of whole plant of Phyllanthus niruri, leaves and fruits of Solanum xanthocarpum and fruits of Solanum melogena may be useful in the treatment and management of diabetes mellitus. (41)
Hematologic Effect: Study evaluated the hematological effects of administering Ipomoea batatas and Phyllanthus niruri in the ICR mice. Results showed P. niruri can increase RBC, hematocrit, and hemoglobin. There were no significant effects noted on WBC count, absolute granulocyte, lymphocyte, and monocyte counts, and platelet counts. Study suggests the effect of I. batatas and P. niruri on different hematologic parameters are due to folic acid and iron which are integral components in the production of RBC and hemoglobin. (
• Acute Oral Toxicity Study: Study evaluated the acute oral toxicity (LD50) of aqueous extract of P. niruri in Swiss albino mice with regards biochemical and cyto-architectural alterations in the kidney. LD50 was 2590.984 mg/kbw. There was observed elevation of serum level of urea at higher doses, with histological alteration at doses higher than 2500 mg/kbw.

Phytochemicals extracted from dried plant material were applied to HCV-infected cell lines to determine effect on viral load and cell toxicity. Results showed significant decrease in the number of viral copies per cell with no significant toxicity. Results suggest different extracts may exhibited different kinetics and different mechanisms of actions. Study suggests potential for the development of novel treatments and alternative drug options for HCV patients. (59)
• Wound Healing / Anti-Ulcer / Aerial Parts: Study evaluated the wound healing and antiulcer properties of extract of aerial parts in experimental wound and ulcer models in rodents. On excision and dead space wound models, the extract significantly (p<0.05) reduced wound diameter and reduced epithelialization time of excised wounds. In indomethacin-, ethanol acid- and cold restraint stress-induced ulcer models, the extract significantly (p<0.05) inhibited development of induced ulcers. (60)
• HIV-1 Reverse Transcriptase Inhibitory: An aqueous extract of Phyllanthus niruri inhibited human immunodeficiency virus type-1 reverse transcriptase (HIV-1-RT). Inhibitor was identified as repandusinic acid A monosodium salt (RA). RA (2.5µM) inhibited up to 90% of HIV-1 specific p24 antigen production in a Clone H9 cell system. (62)
• Antimalarial / Plasmodium berghei / Whole Plant: Study evaluated
ethanolic, dichlormethane and lyophilized extracts of whole plant of Phyllanthus niruri for antimalarial activity against Plasmodium berghei ANKA in mice. No toxic effect was observed in mice treated orally with any of the extracts at a single dose of 500 mg/kbw or with the same dose given twice weekly for 4 weeks. No lesions were observed grossly or histopathologically. At 200 mg/kg, ethanolic and dichlormethane extracts produced significant chemosuppression of parasitaemia (>60%). The ethanolic extract reduced parasitaemia by 73%. (63)
• Antitumor / Corilagin: Study isolated antitumor components by bioguided fractionation and chromatographic methods from ethyl acetate fraction of P. niruri, which were identified as ethyl brevifolincarboxylate and corilagin.

                                                            List of Understudied Philippine Medicinal Plants
                                          New plant names needed
The compilation now numbers over 1,300 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you know of a plant to suggest for inclusion, native or introduced, please email the info: local plant name and/or English name (if known), any known folkloric medicinal use, scientific name (most helpful), and, if possible, a photo. Your help will be greatly appreciated.
