If you are a healthy person experiencing new onset petechiae for no reason (you haven't been vomiting, straining, or doing something else that would easily explain the condition), you should see a doctor about it. Though petechiae usually go away on their own if you don't have another disease, it's best to find out if they have an underlying cause. It's especially important to take your child to the doctor if she gets petechiae for no reason that you can see, and if it covers a large part of her body. If you have an infection or disease that causes your petechiae, the best way to treat the petechiae is to try to cure the disease. Your doctor can help you decide what medication is best for your disease. In older people who's blood clotting system is naturally less effective, even minor trauma can cause significant petechiae. One way to prevent petechia if you're older is to try to avoid trauma. Of course, sometimes you can't avoid an injury, but do not take unnecessary risks. For instance, if you have trouble balancing properly, consider using a cane or walker. This may cause petechiae due to trauma, injury, or straining to disappear, but it will not treat any underlying conditions which cause petechiae. Cold can help cut down on inflammation and can help reduce future petechiae, as well. To make a cold compress, wrap an ice pack in a washcloth or towel and hold it against the area with petechiae 15 to 20 minutes or less if you can't stand it that long. Do not put an ice pack directly on your skin, as it can cause damage to your skin. You can also just use cool water on a washcloth held up to the area. The main way to get rid of petechiae is to wait for them to heal on their own. Once you treat the underlying cause, the petechiae should fade away.

Problem: Article: Check with your local nursery or an Asian market to see if they carry jackfruit seeds. If not, you can find seeds available to purchase online. If you have access to ripe jackfruit, you can also harvest seeds from the fruit. Rinse the seeds with warm water to remove the sticky pulp. Place your seeds in a bowl or container with lukewarm water. Let them sit for a full day before sowing them. Soaking seeds will speed up the germination process and make your seedlings grow faster. Use a plastic pot with drainage holes so water can easily flow out from the bottom. Use a well-draining potting mix with perlite, sand, and organic compost to achieve the best drainage in your pot. Premixed potting soil can be purchased at gardening stores, or you can make your own. Space the seeds evenly near the center of the pot. Don't let the seeds grow near the edges, otherwise the roots may not develop fully. Cover the seeds and press down slightly to compact the potting mix. You can plant more seeds in the pot, but they will be competing for resources and may not grow as well. Keep the soil moist, but make sure that it is not overwatered. Stick your finger into the soil up to the first knuckle to feel if it's wet. If it isn't, water the seeds. Even though jackfruit grows in humid, tropical regions with a lot of rainfall, too much water can cause the seeds and roots to rot. Try to use untreated or distilled water when starting off your seedlings. If you can, keep the pot outdoors during the warmest parts of the day. When the temperature gets near freezing, bring the pot indoors and keep it on a windowsill or near a window so it receives sunlight. A heat lamp indoors is a great substitute if the weather outside is not cooperating. It will take 2-3 weeks for your seedlings to germinate. Look for seedlings that have grown the tallest and have healthy looking leaves. Remove the weaker seedlings by gently pulling them out of the soil. Avoid using seedlings that are spindly or have grown near the edge of the pot. Their root systems will not have spread and developed fully.
Summary:
Purchase jackfruit seeds. Soak the seeds in water for 24 hours. Fill a 1USgal (3.8L) pot with potting mix. Plant 3 seeds 1in (2.5cm) deep in the soil. Water the seeds every day. Keep the pot in a warm, sunny area. Thin down to 1 healthy seedling after they've started germinating.
