Dog Blood Bush: Benefits, Side Effects, and What It Really Does for Fertility
By Dr. Rojae Hazel, Hazba Medical Center, Falmouth
Ask any Jamaican grandmother about getting pregnant and there's a good chance dog blood bush comes up. It's one of the best-known "fertility bushes" in Jamaican folk medicine, sold in markets, on Amazon, and in tea bags across the diaspora.
As a doctor who works with women trying to conceive, I get asked about it often. Here's an honest look at what dog blood bush is, how people use it, what it can and can't do, and when it's time to look beyond the teapot.
What Is Dog Blood Bush?
Dog blood bush is the Jamaican name for Rivina humilis, a small shrub also called pigeonberry, rougeplant, or bloodberry. It gets its name from its bright red berries, which contain a deep red pigment that stains like blood.
It grows wild across Jamaica, the wider Caribbean, and the Americas. The leaves are the part usually used for tea.
Don't confuse it with Jamaican dogwood. Jamaican dogwood (Piscidia piscipula) is a completely different plant. It is a strong sedative, traditionally used as a fish poison, and it is not safe to drink casually. If you're buying online, check the botanical name says Rivina humilis.
Dog Blood Bush Benefits
In Jamaican bush medicine, dog blood bush is traditionally used to:
Support fertility and "clean out" the womb
Regulate periods
Ease colds and chest complaints
Help wounds heal when applied to the skin
Lab studies on Rivina humilis have found antioxidant, anti-inflammatory, and antimicrobial activity in the plant. That's a promising start. But lab results in a test tube are not the same as proof that the tea works in the human body.
Can Dog Blood Bush Get You Pregnant?
This is the question most people really want answered. There are no human clinical studies showing that dog blood bush improves fertility or helps you get pregnant. Its reputation comes from generations of traditional use and personal stories, not medical research.
That doesn't mean it's worthless. Many women find that a herbal ritual helps them feel more in control during a stressful time. But if you've been trying for a while, it's important to know that no tea can:
Open a blocked fallopian tube
Fix fibroids or polyps inside the womb
Correct a hormone problem like PCOS on its own
Fix a sperm problem on your partner's side
These are some of the most common causes of infertility, and they need proper testing to find.
When to see a doctor: If you're under 35 and have been trying for 12 months, or over 35 and trying for 6 months, it's time for a fertility check. At Hazba Medical Center we offer fertility assessments, ultrasound, hysteroscopy, and fallopian tube recanalization (a procedure to open blocked tubes), IUI and more. Book a fertility consultation →
How to Boil Dog Blood Bush Safely
Traditionally, dog blood bush tea is made like this:
Rinse a small handful of fresh leaves (or 1–2 teaspoons of dried leaves) well.
Bring about 2 cups of water to a boil.
Add the leaves, lower the heat, and simmer for 5–10 minutes.
Strain and drink warm.
Use the leaves only. The berries are not traditionally eaten and are reported to be toxic.
When Is the Best Time to Drink Dog Blood Bush Tea?
Many women traditionally drink it in the days after their period ends and before ovulation, as a "womb cleanse." There's no research establishing an ideal time or how long it takes to "work," so treat any timing advice you see online as tradition, not science.
Can I Drink Dog Blood Bush Tea on My Period?
There's no evidence that it's harmful during your period, but it also hasn't been studied. If you notice heavier bleeding or cramping after drinking it, stop and speak with a doctor.
Can Dog Blood Bush Stop Your Period or Cause an Abortion?
There's no scientific evidence that dog blood bush stops periods or ends a pregnancy. However, its safety in pregnancy has never been tested. If you are pregnant or could be pregnant, don't drink it. Never use any herb to try to end a pregnancy; it can be dangerous. Please speak to a doctor about your options.
Dog Blood Bush Side Effects
Because it hasn't been properly studied in people, side effects aren't well documented. To stay safe:
Avoid it if you're pregnant or breastfeeding
Don't eat the berries
Check with your doctor if you take regular medication or have kidney or liver problems
Stop if you get stomach upset, rash, or unusual bleeding
Can Men Drink Dog Blood Bush Tea?
Yes, men do drink it traditionally, and there's no known reason it's unsafe for healthy men in normal amounts. But there's no evidence it improves sperm health. If you and your partner are trying to conceive, a semen analysis is one of the simplest and most useful first tests.

The Bottom Line
Dog blood bush is a much-loved part of Jamaican tradition, and for many women it's a comforting part of the journey to motherhood. But it isn't a proven fertility treatment. Enjoy it if it feels right for you, use it safely, and don't let months or years pass without getting checked. Many causes of infertility are very treatable once you know what they are.
