Badara (Indian Ber) in Ayurveda: Properties & Everyday Use

What it is

Badara in Ayurveda is the Indian ber, Ziziphus mauritiana Lam. (family Rhamnaceae), the species behind the API's Kola monographs.

The Ayurvedic Pharmacopoeia of India (Part I, Vol. 3) lists its Kola (badara) monographs, fruit pulp and stem bark, as Zizyphus jujuba Lam.: Lamarck's name, which modern taxonomy treats as a synonym of Ziziphus mauritiana Lam. (Indian ber), not of Miller's Chinese jujube Z. jujuba Mill. (Flora of China; Kew POWO). The three human trials below all used Chinese-jujube (Z. jujuba Mill.) preparations; their results do not transfer to the ber, which has almost no human-trial record.

So when this article says "jujube" from here on, it means the Chinese jujube: the red-date tree (eFloras Chinese Plant Names: description from Flora of China), a different plant from badara entirely. Keep the two apart and everything below reads correctly.

Classical properties

• Taste (rasa): sweet (Madhura), sour (Amla)
• Qualities (guna): heavy (Guru), oily (Snigdha)
• Potency (virya): cooling (Sheeta)
• After digestion (vipaka): sweet (Madhura)
• Doshas: traditionally said to settle Vata and Pitta; may increase Kapha

Traditional use

Classical Ayurvedic texts are describing the ber here, not the Chinese red date. The Bhavaprakasha Nighantu places badara in its Amaradi varga, distinguishing several types, including sauvir (large, sweet, ripe fruit) and kola, and describes the ripe fruit as cooling (shita), mildly purgative in action (bhedana), nourishing, and used for burning sensations, thirst, and wasting (NIIMH e-Nighantu, the CCRAS portal hosting the Bhavaprakasha Nighantu). These are traditional claims, not clinical proof. And they describe the ber. The trials assessed separately below tested a different species.

Now the paragraph that belongs to that different species. In Traditional Chinese Medicine, dried Chinese-jujube fruit is a long-used herb for calming the mind, nourishing the blood, and strengthening the spleen and stomach. The seeds are used for sleep complaints, and the seed preparation suanzaoren is associated with the sour-date form Z. jujuba var. spinosa (MDPI review; Mahmoudi et al. 2020). It stays in this article only so the two plants never get confused again. Nothing in the TCM literature is evidence for badara.

What research has looked at

One sentence to carry through this whole section: every trial below tested Chinese jujube. Not one tested the ber.

Chronic constipation (adults)

In a 2008 double-blind randomized controlled trial (Digestion), 37 adults with chronic idiopathic constipation and prolonged gut transit time received a liquid Chinese-jujube (Z. jujuba) extract or placebo for 12 weeks (Naftali et al., primary paper; PubMed record). Transit time fell from 12.2 to 3 marker particles by week 11 in the jujube group, symptom-severity ratings dropped (6 to 2 vs. 6.2 to 5 on placebo), and quality-of-life scores improved more than with placebo. The weakness is hard to miss: 16 of 19 placebo patients dropped out due to severe constipation (vs. 2 of 18 on jujube), which limits what can be concluded. One small trial, promising, not conclusive. And about Chinese jujube, not the ber drug.

Pediatric functional constipation

A 2025 double-blind randomized trial (Scientific Reports) compared a Ziziphus jujuba Mill. fruit-extract syrup with polyethylene glycol (PEG) in children aged 2–10 with functional constipation over 12 weeks. 62 of 90 enrolled children completed the trial (primary paper). The jujube-syrup group had a better therapeutic response at every follow-up (p=0.001), higher defecation frequency, less fecal encopresis, and lower pain scores, but no significant difference in stool consistency. No drug-related complications were reported in the jujube group, and adherence was better than with PEG. One center, one trial: it needs replication, and it is not a treatment. Never use it in place of, or alongside, prescribed medicine without your doctor. And again, this was Chinese jujube, not badara.

Sleep (postmenopausal women) — seed capsules, variety unspecified

In a 2020 double-blind randomized trial, 106 postmenopausal women in Iran took jujube seed capsules or placebo for 21 days; 96 completed (Mahmoudi et al.). Pittsburgh Sleep Quality Index scores improved in both groups but significantly more in the jujube group (p<0.001). Two caveats we keep coming back to: this tested the seed, not the fruit pulp eaten as badara, and the paper does not specify the botanical variety. The seeds came from local Iranian spice stores and were authenticated at a university herbarium. Do not read this as proof that eating jujube fruit improves sleep, and certainly not as proof about the ber.

What the evidence does not support (yet)

Broader claims, for diabetes, cancer, immunity, or liver protection, rest on laboratory and animal work. A 2024 review of jujube pharmacology found that most research is preclinical (cells and animals), with few human studies among the papers included (MDPI review). Small clinical studies in type 2 diabetes have reported improved glycemic markers, but that evidence is preliminary too.

A 2025 systematic review and meta-analysis pulled together 7 clinical studies with 483 participants on jujube's effects on lipids, glycemic markers, and liver function. It found some signals, but judged the overall quality of the evidence limited (PubMed PMID 40399274). And to say it once more: all of this is Chinese-jujube evidence.

Safety notes

• The ber has almost no human-trial safety record. Everything below about tolerability comes from small Chinese-jujube trials. Do not read it as ber safety data.
• Well tolerated in the small Chinese-jujube trials. The pediatric trial reported no drug-related complications in the jujube-syrup group, and the review of the adult constipation trial notes no changes in liver or kidney function and no other adverse effects (Scientific Reports 2025; MDPI review).
• Chinese jujube fruit is a widely eaten food, consumed fresh and dried, including in TCM dietary use, but that does not establish the safety of concentrated extracts or seed capsules, and it says nothing about the ber (MDPI review).
• No trial data in pregnancy or breastfeeding for ber preparations, jujube extracts, or seed capsules, so discuss with a clinician first.
• People with diabetes should note jujube is a naturally sweet fruit and count it toward carbohydrate intake; blood-sugar benefits are not established in humans.

FAQs

Does badara help with sleep?

There is no trial of the ber for sleep, so the honest answer starts there. What exists is a 21-day RCT of Chinese-jujube seed capsules in 106 postmenopausal women, which improved sleep-quality scores significantly more than placebo (Mahmoudi et al.). Wrong plant part, unspecified variety, wrong species, one small trial. We would not build any sleep claim for badara on it.

Does jujube help constipation?

Two small trials say maybe, about Chinese jujube. A 12-week double-blind RCT in 37 adults found liquid Z. jujuba extract improved transit time and symptoms versus placebo (Naftali et al. 2008), though the placebo group's heavy dropout limits conclusions. And a 12-week pediatric RCT in 62 children compared jujube syrup with PEG and reported a better therapeutic response in the jujube group (Scientific Reports 2025). Both are preliminary and need replication, and neither tested the ber. Never use it in place of, or alongside, prescribed medicine without your doctor.

Is jujube safe for children?

The evidence is limited, and it is Chinese-jujube evidence. The 12-week pediatric trial (62 children completing) reported no drug-related complications in the jujube-syrup group (Scientific Reports 2025), but that is one trial at one center, of a different species than badara. Persistent constipation in a child deserves a pediatrician's assessment.

Is badara the same as Indian ber?

In Ayurvedic usage, badara is the Indian ber: the API's Kola monographs are listed as Zizyphus jujuba Lam., which is a synonym of Ziziphus mauritiana Lam., not of the Chinese jujube Z. jujuba Mill. The trials above all used Chinese-jujube preparations; their results do not transfer to the ber.

Can people with diabetes eat jujube?

Jujube is a sweet fruit, so count it as part of carbohydrate intake. Small clinical studies in type 2 diabetes have reported improved glycemic markers, but the evidence is preliminary, and the 2025 meta-analysis judged the overall quality of that evidence limited (PMID 40399274). Do not treat jujube as a blood-sugar therapy; discuss it with your clinician (MDPI review).
