Benefits
Quality-of-life ratings in peri- and postmenopausal women
In a 16-week placebo-controlled study of 197 healthy women aged 40 to 60, a 400 mg daily water extract improved self-rated memory and concentration, vasomotor symptoms, menstrual symptoms and sleep problems more than placebo. The outcomes were subjective questionnaires in a single population, and the proprietary extract was supplied by its maker.
Menopausal symptom and hot flush reports with a combined herbal formula
A 24-week placebo-controlled study in 119 peri- and postmenopausal women tested a formula combining this extract with Eurycoma longifolia. Menopause rating and quality-of-life scores improved in both the herbal and placebo groups, and the drop in hot flushes was not significantly greater than placebo. The product was a two-herb blend funded by its maker.
Waist size and body weight in adults carrying excess weight
In a 16-week phase 2 trial in 133 adults with obesity, a standardized extract taken at 750 mg a day lowered body weight, body mass index, waist circumference and waist-to-height ratio compared with placebo, with larger waist effects at the higher dose. The trial was conducted and funded by the extract's maker.
Cholesterol and triglyceride measures during menopause
In the 16-week study, total and LDL cholesterol improved versus placebo, and in a 6-month pilot in 63 postmenopausal women triglycerides were lower than placebo. In that pilot, blood pressure, body mass index, fasting blood sugar and most other measures did not differ from placebo, and the lipid changes were small.
Reproductive hormone levels in postmenopausal women
Postmenopausal women taking the water extract showed no change in luteinizing hormone, follicle-stimulating hormone or estradiol compared with placebo, and blood counts and clinical chemistry stayed within normal ranges. This points to effects on wellbeing ratings without a measurable shift in circulating sex hormones.
Mechanism of action
Phytoestrogen activity in laboratory studies
The plant contains flavonoids, phenolic acids including gallic acid, and saponins. In cell studies an extract showed estrogen-like activity, raising responses in estrogen-sensitive human cells grown without estrogen. Whether this carries over to estrogen-like effects in people is not established, and the human trials found no change in sex hormone levels.
Antioxidant and anti-inflammatory actions in the laboratory
Laboratory work attributes antioxidant and anti-inflammatory activity to the plant's flavonoids, ascorbic acid, beta-carotene and phenolic compounds, which can neutralize reactive oxygen species and dampen inflammatory signaling. These are test-tube findings and have not been shown as clinical outcomes in people.
Bone turnover markers in animal models
In ovariectomized rats, a model of estrogen loss after menopause, the extract moved bone turnover markers in a favorable direction, raising osteocalcin and lowering a collagen breakdown marker, although it did not prevent bone calcium loss. These results come from animals and have not been confirmed in human bone studies.
Clinical trials
Randomized, double-blind, placebo-controlled 16-week trial of a 400 mg/day Labisia pumila var. alata water extract in healthy women aged 40 to 60 in Malaysia (Norhayati et al. 2014, J Med Food).
197 healthy pre- and postmenopausal women aged 40 to 60 (102 extract, 95 placebo).
Compared with placebo, the extract group reported better memory and concentration, vasomotor symptoms, menstrual symptoms and sleep, plus improvements in total and LDL cholesterol. Reproductive hormones (LH, FSH, estradiol) did not change and safety labs stayed normal. The quality-of-life outcomes were self-rated questionnaires.
Randomized, double-blind, placebo-controlled 6-month pilot of a Labisia pumila var. alata water extract at 280 mg/day in postmenopausal Malay women (Abdul Kadir et al. 2012, Evid Based Complement Alternat Med).
63 postmenopausal women (29 extract, 34 placebo).
Triglycerides were lower with the extract than placebo after 6 months. Blood pressure, body mass index, waist circumference, fasting blood sugar, other lipids and reproductive hormones did not differ significantly between groups. The study was small and described as a pilot.
Randomized, double-blind, placebo-controlled phase 2 dose-ranging trial of the standardized SKF7 extract (375 to 750 mg/day) in adults with obesity, funded by the extract's maker (Swarna Nantha et al. 2023, Diabetes Obes Metab).
133 adults with obesity across several Malaysian clinics.
At 750 mg a day, the extract lowered body weight, body mass index, waist circumference and waist-to-height ratio versus placebo, with waist measures showing a dose-dependent response. The endpoints were body measurements only, and the trial did not enroll women specifically for menopause.
Randomized, double-blind, placebo-controlled 24-week trial of a two-herb formula containing Labisia pumila and Eurycoma longifolia, funded by the maker and with maker employees as authors (Chinnappan et al. 2020, Food Nutr Res).
119 healthy peri- and postmenopausal women aged 41 to 55.
Hot flush, Menopause Rating Scale and quality-of-life scores improved in both the formula and placebo groups, with no significant between-group difference in hot flushes. LH and FSH fell and LDL and triglycerides dropped within the formula group only. This tested a two-herb blend, not the extract alone.
