Two common morning sickness underlying issues are either one of, both or all of 1) B6 deficiency, 2) sluggish liver (all the extra circulating hormones of pregnancy get "backlogged" so to speak) or 3) blood sugar imbalance.
All of these issues can be helped with proper digestion.
The simplest, most often overlook recommendation is to chew your food really well (digestion/eases load on liver), eat B-Vitamin rich foods (B6) and start your morning w/the juice of half a lemon before eating or drinking anything else (gentle liver cleansing), eat grounding and nutrient dense foods (to balance blood sugar).
Along with chewing your food well, eat only what you need to satisfy your hunger (do not overeat as this causes more digestive strain). If you chew your food really well and eat slowly, you will be satisfied much sooner. Eat every meal with chopsticks if that will help slow you down!
Stick to unrefined organic coconut oil and butter for fats because they bypass the liver (avoid all other fats, except primrose, flax and fish oils...these are fine).
Nutrient dense foods will help with blood sugar providing enough nutrients and protein to stabilize.
These basic requirements for good nourishment and digestive wellness address the cause at the level of one's basic needs and lifestyle.
Only after these needs have been met, would it be optimal to add herbs or supplements to the equation, all of which will have a better chance of supporting one through morning sickness while not having to work against deficiencies and not-so-helpful lifestyle habits.
oh and I almost forgot! Get fully hydrated! In some cases morning sickness is due to "drought management"

p.s. To the pregnant lady worried about not having morning sickness, I have two healthy children, not a day of morning sickness with either of them!
