Centella asiatica

Last Update: April 24, 2024.

OVERVIEW

Introduction

Centella asiatica, commonly known as gotu kola or Asian pennywort, is a herbaceous, flowering, perennial plant native to tropical areas of Southeast Asia and Australia and used as a food as well as in traditional medicine. While generally regarded as safe, Centella has been linked to rare instances of clinically apparent acute liver injury with jaundice.

Background

Centella also known as gotu kola, tiger grass or Indian pennywort is made from fresh or dried leaves of Centella asiatica a creeping herbaceous, flowering plant native to tropical swampy areas of Southeast Asia and Australia but now found in many tropical and subtropical areas of the world. It is eaten as a vegetable and in salads and has been used for centuries in traditional Ayurvedic and Chinese medicine for a large variety of conditions. Centella extracts contain more than 100 constituents including polyacetylenes, flavonoids, flavones, sterols and lipids. The active ingredients are thought to be the pentacyclic triterpenoid glycosides, asiaticoside, centelloside, and madecassoside, and their aglycones, asiatic acid and madecassic acid. In vitro and in vivo studies suggest that these triterpenoids have anxiolytic, antiinflammatory, antioxidant, antiulcer, anticancer, neuroprotective, and wound healing properties. In traditional medicine, gotu kola has been used to treat a wide variety of conditions including minor wounds, psoriasis, cellulitis, chronic venous insufficiency, ulcers, hypertension, bronchitis, asthma, kidney disorders, urethritis, edema, diabetic microangiopathy, obesity, leprosy, smallpox, syphilis, and miscellaneous liver, kidney, pulmonary, and heart diseases. It is purported to promote immune function, to extend longevity, and to boost memory and cognitive function. However, none of these properties have been proven in prospective, controlled trials in humans, and Centella asiatica is not approved in the United States as therapy of any medical condition. Nevertheless, it is widely available as capsules, tablets, powders, solutions, and skin creams in over-the-counter herbal products. The typical oral dose is 60 to 120 mg daily of purified extracts, but may be 600 to 1800 mg daily of capsules or powders of dried leaves. Centella has few if any adverse events and no known proven severe adverse effects. In small trials, Centella asiatica extracts have appeared to be well tolerated with only mild, transient, and nonspecific adverse effects (headache, dizziness, bloating, diarrhea, nausea), which often have been similar in frequency among persons receiving placebo or alternative treatments. Rare instances of allergic reactions have been reported, particularly with topical therapy of skin diseases and wounds. Hepatotoxicity has also been reported but is very rare.

Hepatotoxicity

Centella extracts have not been linked to serum enzyme elevations during therapy, although there have been few prospective studies in humans that have reported on laboratory test results during treatment. Nevertheless, rare instances of acute and symptomatic liver injury have been published, including a case series in 2008 of three Argentinian women who developed liver injury with jaundice after use of centella for weight loss (Case 1) and a single short case report from Switzerland in 2011 after its oral use for acne. The time to onset ranged from 3 to 8 weeks and the injury was described as hepatocellular, resolving completely within 1 to 2 months after stopping. Immunoallergic and autoimmune features were present in some cases. The possibility of contamination or presence of other potential hepatotoxins in the commercial products was not ruled out in the clinical reports of hepatotoxicity of centella.

Likelihood score: C (probable rare cause of clinically apparent liver injury).

Mechanism of liver injury

The mechanism of liver injury attributed to Centella asiatica is not known, but the rare events suggest idiosyncratic, perhaps immune mediated injury due to one of the many components of the herb or one of its metabolites.

Outcome and Management

Gotu kola hepatotoxicity is generally self-limited and only mild-to-moderate in severity. Appearance of clinically evident liver injury developing during therapy should lead to prompt withdrawal of the herbal product. Rechallenge should be avoided.

CASE REPORT

Case 1. Acute granulomatous hepatitis developing during weight loss treatment with Centella asiatica. (1)

A 61 year old previously healthy woman developed abdominal pain, arthralgias, and weakness followed by dark urine and jaundice after taking tablets of Centella asiatica for 30 days as a weight loss agent. On examination she was jaundiced and had tender hepatomegaly. Laboratory tests (Table) showed marked elevations of serum ALT and AST (30 and 26 times the upper limit of normal [ULN]) with mild elevations in alkaline phosphatase (1.7 times ULN) and bilirubin (4.2 mg/dL). Viral serology showed no evidence of hepatitis A, B or C, while autoantibody testing showed high titers of SMA (1:160) and AMA (1:320) with no detectable ANA or anti-LKM, and normal total globulin levels. Liver ultrasound was normal. A liver biopsy showed an acute hepatitis with granulomas. She was treated with ursodiol and recovered. Two months later all laboratory results were normal or negative including SMA and AMA. She did well until 7 months later when she restarted Centella asiatica for two weeks when she developed pain, weakness and jaundice again. Laboratory results were similar to those with the first episode but ANA, SMA and AMA were still negative. A repeat liver biopsy again showed acute hepatitis with granulomatous changes. She was treated with a course of prednisone and ursodiol and again improved.

Comment

A dramatic case of an immunoallergic acute hepatitis arising in an otherwise healthy woman taking a commercial weight loss product said to be Centella asiatica. The clinical history, laboratory tests, liver biopsy, and recurrence on re-exposure provide convincing evidence of drug induced liver injury from the herbal product. At issue is whether the product consisted of Centella asiatica only. The history could also be consistent with other better known herbal causes of acute liver injury such as ephedra, chaparral, germander, garcinia, or green tea. The product name, concentration of centella, number of tablets taken daily, chemical analysis, and even product label were not provided. After these 3 cases from a single referral center in Mendoza, Argentina in 2005, there have been no published case series of injury from Centella asiatica and only a single case report from Switzerland in 2011. Furthermore, the large series of herbal and dietary supplement induced liver injury from around the world, there have been no further described cases.
