5 Peruvian Herbs for Healthy Skin and Hair This Summer

Summer is rough on skin and hair. More sun, more sweat, more chlorine, more salt water. So it is no surprise that people start asking what they can take to help from the inside. Peru has a long list of plants tied to skin and hair in traditional use, and a few of them have early science worth knowing about. We are going to walk through five, and we will be honest about where the evidence is solid and where it is mostly tradition.

One thing to say up front: no herb is going to undo a bad sunburn or regrow a full head of hair. What these plants can do is supply the raw materials and antioxidants your body uses to keep skin and hair in good shape. Think groundwork, not magic.

1. Horsetail (Cola de Caballo): the silica plant

Horsetail is the one most directly tied to hair and nails, and the reason is a mineral called silica. Horsetail is one of the richest plant sources of it, and silica is a building block your body uses for collagen, the protein that gives skin its bounce and hair its strength. In Peru, cola de caballo grows along riverbanks and irrigation ditches, and it has been brewed for generations as a tea for hair, nails, and skin.

The research is early but not empty. A small 2015 study found that a silica-containing supplement improved nail and hair quality in women with thinning hair over several months. That is one modest study, not proof, and horsetail tea gives you less silica than a concentrated supplement. Still, a daily cup is a low-cost, gentle way to work it into a routine.

2. Aguaje: beta-carotene for skin

Aguaje is the orange palm fruit from the Peruvian Amazon, and it is loaded with beta-carotene, the same pigment that makes carrots orange. Your body converts beta-carotene into vitamin A, which skin cells rely on for normal turnover and repair. Amazonian women have treated aguaje as a daily food for generations.

We will push back on one common claim, though. Aguaje is often sold for body curves and hormonal shaping, and that angle runs way ahead of the evidence. The skin story is the more honest one: it is a real source of vitamin A precursors and antioxidants. You can read our fuller take in our Aguaje notes.

3. Camu Camu: vitamin C for collagen

If horsetail supplies silica, camu camu supplies the other half of the collagen equation: vitamin C. Your body literally cannot build collagen without it. Camu camu, a small Amazonian berry, is one of the densest natural vitamin C sources on earth, with fresh pulp carrying many times the vitamin C of an orange by weight.

That matters for skin because collagen production drops as we age and takes a beating from sun exposure. A steady supply of vitamin C is part of how skin stays resilient. Just keep expectations grounded: vitamin C supports collagen, it does not erase wrinkles. Our Camu Camu powder is an easy way to add it to a morning smoothie.

4. Moringa: antioxidants by the leaf

Moringa is the nutrient-dense green powder that has gotten a lot of attention worldwide, and Peru grows it too. For skin, the interesting part is its antioxidant load: vitamin E, vitamin A precursors, and a range of polyphenols. Antioxidants help your skin handle the oxidative stress that comes with sun and pollution, which is exactly the kind of stress summer piles on.

The honest caveat is that most moringa skin research has been done on topical extracts and in the lab, not on people drinking it. Eating moringa is a solid way to top up antioxidants generally. Crediting it specifically for glowing skin is a stretch the science has not earned yet.

5. Sangre de Grado: the topical one

Sangre de grado, or dragon's blood, is the red sap of an Amazonian tree, and unlike the others on this list it is mostly used on the skin rather than swallowed. In the rainforest it has been dabbed on cuts, bites, and blemishes for centuries. It is rich in proanthocyanidins and a compound called taspine that lab studies have linked to wound closure.

This is the one with the most direct skin tradition, but also the one to use with the most care. It stains, it is potent, and a patch test on a small area is smart before you put it anywhere visible. It is a spot treatment, not a daily face routine.

A realistic way to use them

You do not need all five. A common starting point is horsetail tea for hair and nails plus a vitamin C source like camu camu for skin, which covers both sides of the collagen story. Add aguaje or moringa if you want more antioxidant support, and keep sangre de grado as a targeted topical. You can browse the full range in our general wellness collection.

Cautions worth reading

Horsetail contains small amounts of a compound that breaks down thiamine (vitamin B1), so it is not meant for daily long-term use without breaks, and it is not recommended in pregnancy. People with kidney conditions should check with a doctor before drinking it regularly, since it has a mild diuretic effect. Aguaje has plant compounds with weak estrogen-like activity, so anyone with a hormone-sensitive condition should ask their doctor first. And sangre de grado should be patch-tested and kept away from broken skin near the eyes. None of these are a substitute for sunscreen, sleep, and water, which still do more for your skin than any herb.
