Lodhra: Traditional Uses, Evidence & Safety

TL;DR

Lodhra (Symplocos racemosa) is the dried stem bark of an evergreen tree, used in Ayurveda for menstrual bleeding, leucorrhoea, diarrhea, and eye disorders. Evidence is almost entirely preclinical: antimicrobial, anti-inflammatory, and wound-healing effects in lab and animal studies. A small study of a lodhra-containing multi-herb formulation reported less menstrual blood loss; no high-quality trials of lodhra alone were identified.

What it is

Lodhra is the dried stem bark of Symplocos racemosa Roxb., an evergreen tree (growing to about 6 m) in the Symplocaceae, a family made up of the single genus Symplocos, distributed across tropical and subtropical Asia (PMC phytochemistry paper). Most pharmacological work has focused on the stem bark, the part used medicinally (J Ethnopharmacol review). Phytochemical studies have identified phenolic glycosides (notably symplocoside), triterpenoids (betulinic acid, acetyloleanolic acid, oleanolic acid), and flavonoids such as quercetin in the bark (same review).

Traditional use

In Ayurveda, the astringent bark of lodhra has been used for uterine disorders, menorrhagia (heavy menstrual bleeding), leucorrhoea, diarrhea, dysentery, and eye disease: as a single drug or as an ingredient of multi-component preparations (PMC review of traditional uses). Ethnobotanical literature additionally records use for liver and bowel complaints, skin diseases, bleeding gums, fever, and gonorrhea (J Ethnopharmacol review). These are traditional claims, not clinical proof: the research evidence is assessed separately below.

What modern research says

Phytochemistry and preclinical activity

A 2016 comprehensive review in the Journal of Ethnopharmacology found that nearly all pharmacological reports on lodhra concern the stem bark and come from laboratory (in vitro) and animal (in vivo) studies: reported effects include anticancer, hepatoprotective, antioxidant, anti-androgenic, anti-inflammatory, wound-healing, and antidiabetic activity (Acharya et al., 2016). The review's conclusion is candid: while many ethnobotanical claims were supported by these in-vitro and in-vivo studies, the mode of action still needs to be established and the traditional claims validated in clinical practice after proper safety assessment (same review). In other words, the lab work is real, but human proof is missing.

Heavy menstrual bleeding (small open-label study of a multi-herb formulation)

A small open-label clinical study (n=30) tested a four-herb Unani formulation containing lodhra, alongside Khurma (Phoenix dactylifera), Rasaut (Berberis aristata), and Talmakhana (Asteracantha longifolia), given as 3 g of powder with 2 g sugar twice daily for seven days per cycle over three consecutive cycles (Shahmeer & Shameem, 2020). Among participants, 86.7% achieved a 30–50% reduction in menstrual blood loss (p<0.001) and 56.7% a reduction in bleeding duration (p<0.001). Improvement in hemoglobin (16.7%) was not statistically significant (p=0.228), while quality-of-life scores improved (p<0.001) (same study).

Read carefully: this study had no control group, and lodhra was one of four ingredients, so lodhra's individual contribution cannot be separated out. It is a signal from a formulation study, not evidence that lodhra alone reduces menstrual bleeding.

What the evidence does not support (yet)

No placebo-controlled randomized trials of lodhra as a single herb were identified in the literature search for this article. Claims about PCOS, hormone balancing, or skin effects rest on traditional use and preclinical work only.

Dosage

There is no established single-herb dose for lodhra. The only clinical study located tested lodhra as one ingredient of a four-herb formulation (3 g of the total formulation powder twice daily), not lodhra alone, so no lodhra-specific dose can be drawn from it. Classical multi-herb preparations containing lodhra are dispensed under Ayurvedic practitioner guidance; do not self-prescribe.

Safety & contraindications

No dedicated human safety trials of lodhra were identified, and the 2016 Journal of Ethnopharmacology review concludes that proper safety assessment is still needed before clinical validation (Acharya et al., 2016). Heavy menstrual bleeding can signal serious underlying conditions: it should be evaluated by a clinician, not self-treated with herbs. Avoid use in pregnancy and breastfeeding (no safety data), and talk to a qualified practitioner before use, especially if you take medications that affect bleeding.

FAQs

What is lodhra used for in Ayurveda?

Traditionally, lodhra bark is used for uterine disorders including heavy menstrual bleeding (menorrhagia) and leucorrhoea, as well as diarrhea, dysentery, and eye disease: either alone or in multi-herb preparations (PMC review). These are traditional uses, not clinically proven effects.

Does lodhra reduce heavy menstrual bleeding?

One small open-label study (n=30, no control group) of a four-herb Unani formulation containing lodhra reported 30–50% less menstrual blood loss in most participants (Shahmeer & Shameem, 2020). Because lodhra was one of four ingredients and there was no placebo comparison, this does not prove lodhra itself works. No trials of lodhra alone were identified.

No. No pharmacopoeial or clinical-trial dose for lodhra as a single herb was identified. The one clinical study used lodhra only as part of a multi-herb formulation, so it cannot establish a lodhra dose.

Is lodhra safe?

Human safety data are essentially absent: no dedicated safety trials of lodhra were found, and a 2016 review states proper safety assessment is still needed (Acharya et al., 2016). Heavy bleeding should be medically evaluated rather than self-treated.
