Frequently asked questions

Cleavera is a liquid herbal dietary supplement made with four botanicals traditionally used to support healthy lymphatic flow:* cleavers, red clover, stillingia and prickly ash. The herbs are extracted in vegetable glycerin and water, so the formula is alcohol-free. Each 2 fl oz (59 mL) amber glass dropper bottle holds 59 servings.

Here’s the honest answer. Cleavers, red clover, stillingia and prickly ash have a long history of traditional use in Western herbalism to support healthy lymphatic flow and circulation.* But Cleavera’s formula hasn’t been tested in clinical trials, and no published study shows what a combination herbal drop does to lymph. Lymph moves mainly with muscle movement, breathing and hydration, so think of the drops as one part of a daily routine, not a proven fix.

Your lymphatic system is a network of vessels, nodes and organs that collects extra fluid from your tissues and returns it to your bloodstream. Unlike blood, lymph has no central pump. It moves mainly with muscle movement, breathing and the gentle contractions of the vessels themselves, which is why everyday habits like walking, deep breathing, drinking water and good sleep matter.

Most herbal tinctures are made with ethanol. We extract our herbs in vegetable glycerin and water instead, which gives a mild, naturally sweet liquid with no alcohol burn. It’s an easy fit if you avoid alcohol or simply prefer a gentler taste.

See Glycerite vs Tincture for how the two compare.

Mild, earthy and lightly sweet from the vegetable glycerin, with a gentle warming note from prickly ash. Because there’s no alcohol, there’s no burn, and it blends easily into water or tea.

Yes. The formula is vegan, gluten-free and non-GMO, and it’s made without alcohol, artificial colors, artificial flavors or added sugar. The finished product is tested by an independent third-party laboratory for quality and purity before it ships.

Take 1 mL twice daily. Add it to your favorite drink, such as water, tea, juice or a smoothie, or take it straight. For best results, use it consistently and stay hydrated throughout the day.

One mL is about ¼ teaspoon. Fill the dropper to 1 mL, or measure ¼ teaspoon if that’s easier.

Please don’t exceed the suggested serving of 1 mL twice daily. With herbal supplements, more isn’t better. Follow the directions on the label, and ask your healthcare professional if you have questions about what’s right for you.

Each 2 fl oz (59 mL) bottle holds 59 one-mL servings, which is about 30 days at two servings a day. The Duo Bundle covers about 60 days, the 90-Day Ritual Bundle about 90 days and the Six-Month Supply about 180 days. Compare bundles.

Store the bottle in a cool, dry place away from direct sunlight, and cap it tightly after each use. For shelf life, check the expiration date printed on the bottle and use it before that date. Keep out of reach of children.

Everyone is different, and individual results vary. Herbal supplements are meant for steady, consistent use, so we suggest taking Cleavera daily for at least three to four weeks, alongside water, movement and rest, before you decide. Your first order has a 60-day money-back guarantee, so you have time to find out.

Each 1 mL serving contains a 300 mg proprietary blend of cleavers aerial parts (Galium aparine), red clover flower (Trifolium pratense), stillingia root (Stillingia sylvatica) and prickly ash bark (Zanthoxylum americanum). The other ingredients are vegetable glycerin and water.

No. There’s no alcohol, no added sugar and no artificial colors, flavors or sweeteners. The mild sweetness comes from vegetable glycerin, which is also what we use to extract the herbs.

Please talk to your healthcare professional before using Cleavera if you’re pregnant, trying to become pregnant or nursing. Red clover contains naturally occurring plant isoflavones, and herbal supplements aren’t one-size-fits-all.

Check with your doctor or pharmacist before use if you take any medication, especially blood thinners or hormone therapy, or if you have a hormone-sensitive or bleeding condition. Red clover contains plant isoflavones, so it’s worth the conversation. Bring the bottle along so they can see the full ingredient list.

No. Cleavera is for adults only. Keep the bottle out of reach of children.

Talk to your healthcare professional before use if you have surgery scheduled, and let your surgical team know about every supplement you take. They can tell you when to stop and when it’s fine to start again.

Stillingia root, also called queen’s root, has traditionally been used only in small amounts and as part of a blend, which is how it appears in Cleavera alongside three other botanicals. Follow the directions on the label and don’t exceed the suggested serving.

Stop using it if you experience nausea or digestive upset, and contact your healthcare professional if symptoms don’t settle. We’d also like to know: email hello@cleavera.com. You can also report a side effect to FDA MedWatch.
