Both ginger and turmeric are generally considered safe and without significant side effects, and both are available as capsules from health-food stores. However, each may interact with certain prescription medications, and neither should be taken if you are pregnant. Do not self-treat with either ginger or turmeric.
Think of the leather in your car as skin that needs to be cleaned, conditioned, and protected to maintain a healthy appearance. Similar to our skin, if we do not take care of leather, it will dry, crack, and eventually break over time. Wrinkles in leather are caused by environmental stress, heat, or damage from regular wear and tear.
I just bought my first really nice car, a BMW 335i, and I want to make sure the leather interior stays pristine. The bulk of wear on leather surfaces comes from the abrasive quality of built-up dirt, but cowhide also loses essential oils and UV protectants over time that need to be replaced. Ignore leather care and the surface finish will dull and cracks will begin to form. Fortunately, it's fairly easy to keep your seats clean. To start, set up a monthly or quarterly interior-maintenance reminder on your phone. There are plenty of one-step cleaner and conditioners on the market, in lotion, spray, or wipe form. They all work roughly the same way: A gentle oil helps remove dirt and keeps the leather supple.
