Can Guinea Pigs Eat Lavender? (Possible Risks & Serving Size)

Lavender is a gorgeous blue-purple flower famous for its nice smell, which creates a relaxation effect. We use lavender scents all the time; simply look at your cosmetics, sprays, perfumes, fabric softeners, and lotions! But, can this flower be food for our herbivore guinea pigs?

Can guinea pigs eat lavender? Guinea pigs can eat lavender, but it has to be in moderation. The lavender has a specific flavor, and its scent is quite calming, so it can even be useful during times of stress for your guinea pigs. Your guinea pig may have some digestive issues if they eat too much lavender, so it’s important to be careful with how much they get. If your guinea pig is healthy, then lavender is safe for them to eat.

If this is a new food for guinea pigs, introduce it slowly in the diet until it gets used to it over time. So far, it seems that lavender is almost a perfect flower as it relaxes and releases a nice smell! However, lavender doesn’t have some special vitamins and minerals that are beneficial for guinea pig’s health and it’s even rich in calcium and sodium. Because of that, we need to be careful with serving sizes.

Before we feed guinea pigs some lavender, let’s see all the pros and cons and some other facts about lavender. Let’s begin!

Health Benefits of Guinea Pigs Eating Lavender

Health Benefits of Guinea Pigs Eating Lavender

Calming Effects

Lavender is famous for the calming effect that comes from the scent. For this purpose, lavender is mostly used in tea, balms, and lotions. As an essential oil – the options are limitless.

It’s been used in traditional medicine for centuries to treat anxiety, stress, insomnia, depression, and headaches. Lavender also has a calming effect even when it’s consumed.


Lavender has a compound called limonene, which stimulates the enzymes in the stomach and the liver. This process detoxifies the whole body on the inside. It’s also been found by modern research studies to be effective in reducing inflammation and for promoting healthy aging.

Healthy Cardiovascular System

Lavender has zero cholesterol, and this is a good thing. Cholesterol damages the blood vessels because it builds up in them. This increases the risk of heart attack or stroke. Luckily, lavender consumption won’t damage the cardiovascular system or the blood vessels.


Lavender is a great energy source. Just like any food item, lavender has carbs and proteins which are the main energy sources that warm up the body.

Healthy Blood

There is also iron in lavender. This nutrient is extremely important because it fights anemia and keeps the blood healthy.

Risks to Consider When Feeding Lavender to Guinea Pigs

Urinary Problems

Lavender can present possible problems for the urinary tract of guinea pigs because it contains calcium and sodium. Calcium is needed for strong bones, but once the guinea pig is fully grown, it doesn’t need that much calcium. This mineral is useful when the guinea pigs are growing and developing.

If there is excess calcium and sodium in the urinary tract of the guinea pigs, it will pile up as deposits. These deposits can make urination painful, there might be blood in the urine, and also bladder or kidney stones can develop. When this is not treated on time, it can be fatal because it leads to renal failure.

Lack of Vitamins

There are no enough vitamins in lavender, such as vitamin C, vitamin K, vitamin E, and others. Vitamin C is crucial for the overall health of guinea pigs, but sadly, they don’t produce it naturally and can’t store it either.

The guinea pig benefits from any food with vitamin C, or from supplements. Without this vitamin, guinea pigs get scurvy which has awful symptoms: internal bleeding, rough coat, fatigue, diarrhea, loss of appetite, and swollen joints.

Allergic Reactions

Guinea pigs can have an allergic reaction to lavender. The most common allergic reaction from lavender is contact dermatitis, which happens when the skin comes into direct contact with the plant and forms rashes that can look similar to poison ivy.

Other symptoms of lavender allergy include swelling and irritation of the mouth, frequent sneezing, swollen eyes, etc.

Can Guinea Pigs Have Lavender Every Day?

One way to ensure that your pet enjoys the benefits of lavender without risking any allergic reactions is to introduce it gradually! Start by introducing small amounts one time per week. Later, serve lavender in moderation, just a few times per week, not daily, and there will be no risk of health problems.

Lavender will help keep your guinea pig calm, so it may be helpful during times of high stress, such as a visit to the vet or when they’re recovering from illness or surgery.

How Much Lavender Can My Guinea Pigs Have?

You should only give your guinea pigs small amounts of lavender since overfeeding can cause stomach problems or irritation. If this is a new food for the guinea pig, introduce this slowly at first. One little flower bud with the stem is enough for taste.

After some time, you can give 2-3 flower buds tops, but not daily. Always have a good variety of foods in the guinea pig’s diet, so just 1-2 times per week should be enough.

Apart from lavender, guinea pigs can also eat dandelion, marigold, rocket, mint, basil, parsley, oregano, rosemary, thyme, and many other plants.

Lavender oil is a natural remedy used for aromatherapy that has a calming effect on humans and animals.

However, the question remains of is it safe to use lavender oil around guinea pigs?

This statement has been made by some owners, but we recommend taking advice from your veterinarians before using lavender oil on guinea pigs.

Is the Scent of the Lavender Safe for Guinea Pig?

Is the Scent the Lavender Safe for Guinea Pig

The scent of lavender is very calming for humans, but the exposure of a guinea pig to lavender oil should be limited.

That’s because guinea pigs have a great sense of smell and the strong scent of lavender can affect their respiratory system. So, as we have said, it is better to ask your vet if you can use lavender around guinea pigs.

Can Guinea Pigs Eat Dried Lavender?

Guinea pigs are herbivore animals, and they enjoy eating fresh and raw fruits, vegetables, and herbs. So we recommend giving them fresh lavender instead of dried lavender.

Also, it’s important to note that any type of herb should be given to your pet only in moderation. A guinea pig is a small animal, so it would stand to reason that lavender would be toxic in larger quantities.
