Aloe gel is one of the safest natural personal lubricants, according to AlterNet. There are also commercial formulas made from natural and organic materials, such as those made by Sliquid.
Carrageenan, a substance extracted from seaweed, can also act as a natural lubricant, notes AlterNet. However, those using either carrageenan or aloe as lubricants should not rely on them on for long periods, especially when combined with a condom. As these substances dry, they tend to become sticky, which can cause condoms to break.
Coconut oil is another potentially safe personal lubricant, reports Women's Health. However, combining coconut oil with latex condoms can cause the condoms to degrade. Oils also can be difficult to clean out of the vagina and may become rancid or alter the pH levels, explains AlterNet. Mineral oil, sometimes suggested as a natural lubricant, is dangerous because it can contain trace amounts of petroleum.
Some individuals may have allergies or sensitivities to some natural lubricants, notes AlterNet. People should test any new product or ingredient on a less-sensitive area before using it on the genitals. To test the product, the person should apply a small amount to the inside of her elbow and let it sit for a few hours. If there are any signs of irritation, such as redness or itchiness, it is not a good choice.
